What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
How do you solve the equation 720 equals 2a x 3b x 5c?
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
How do you easily balance and solve a scientific equation?
A scientific equation is basically a math equation. Those come in different kinds; each kind needs special techniques for solving. In the simplest case, you have to solve for a single variable; try to transform the equation so that your variable is on the left, and anything else is on the right.
How do you solve an equation with a variable on each side?
It's not always to 'solve' as it is to 'simplify' EX: 15a + 3b = 45c simplifies to 5a + b = 15c
How do you use different techniques to solve linear equations?
1. Elimination: Select two equations and a variable to eliminate. Multiply each equation by the coefficient if that variable in the other equation. If the signs of the coefficient for that variable in the resulting equations are the same then subtract one new equation from the other. If they have opposite signs then add them. You will now have an equation without that variable. Repeat will other pairs and you will end up with one fewer equation and one fewer variable. Repeat this process: after each round you will have one fewer equation and one fewer variable. Keep going until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.2. Substitution: Select a equation and a variable. Make that variable the subject of the equation. The right hand side of this equation is an expression for that variable. Substitute this expression for the variable is each of the other equations. Again, one fewer equation in one fewer variable. Continue until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.3. Matrix inversion: If A is the nxn matrix of coefficients, X is the nx1 [column] matrix of variables and B is the nx1 matrix of the equation constants, then X = A^-1*B where A^-1 is the inverse of matrix A.
How do you solve 3n equals 36?
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
How do you solve algebra equations?
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)
what is algebra ygb-iboe-hvz?
Algebra ygb-iboe-hvz is a type of algebraic equation known as a "ygb-iboe-hvz equation". This type of equation is a type of linear equation that is commonly used to solve for the unknown variable in a given equation. The equation is composed of three terms: ygb, iboe, and hvz. The ygb term is the coefficient of the unknown variable, the iboe term is the constant, and the hvz term is the right-hand side of the equation. To solve the equation, the coefficients of each term must be determined and the equation must be rearranged to solve for the unknown variable.
How cam you determine what two equations' solution is?
Several methods exist. For example: solve one equation for one variable, replace that variable in the other equation. (Two simultaneous equations will often have two variables each.)
Why would you want to solve a literal equation for a variable when you could simply plug in known values and then solve the resulting linear equation?
if you solve by plugging in the known values ahead of time you won't have a general formula for the variable in the literal equation. Therefor if the known values change, you would have to start all over again, making each problem more individualized. Once the literal equation is solved for some variable, if the known values change all you have to do is plug in those new numbers to your literal equation, and out pops your answer
What does each variable stand for in the equation?
The answer depends on the equation!
What is it called when a when you get a variable alone on one side of an equation or inequality in order to solve the equation or inequality?
each of the four regions created on the coordinate plane by the x- and y-axes.
