To explain this, I'll use the example equation: 3x+8=5x-4
To get the variable alone, you must add, subtract, multiply, or divide both sides by the correct numbers to get x on one side. This is easier than it sounds.
First, get x on one side. To do this, subtract both sides by 3x, which gives you:
8=2x-4
Next, you must get all the constants on the other side. To do this, add 4 to both sides, giving you:
12=2x
Finally, you have to remove the coefficient from x. To do that, divide both sides by 2, which gives you:
6=x
Plug that back into your original equation, which gives you:
3(6)+8=5(6)-4
18+8=30-4
26=26
This is a true statement, so we know that we have the correct answer.
When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying
No. In the variable x, alone, it is linear. In the variable y, alone, it is linear. But taken together, in x and y, you have a term which contains xy - that is, a term in which the powers of the unknowns add to 2. So the equation is not linear.
It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
Simultaneous equation* * * * *No, simultaneous equations are two or more equations that have all to be true at the same time (simultaneously) for the solution.An equation with more than one variable is a multivariate equaion.Area = 0.5*Length*Height or a = 0.5*l*h for the area of a triangle has more than one variables, but it is certainly not simultaneous.An equation with a variable is called a single variable equation. An equation that has more than one variable is called as a multi-variable equation. A polynomial equation has one variable in different powers: a common example is quadratic equations.
It is to make the variable the subject of the equation.
A) Divide both sides of the equation by 4.
As it appears, there is no equation but an algebraic term.
To isolate the variable ( m ) in the equation ( 15m + 45 = 0 ), you first subtract 45 from both sides to get ( 15m = -45 ). Then, you divide both sides by 15, yielding ( m = -3 ). Thus, the variable ( m ) is now alone on one side of the equation.

isolate the variable
Divide both sides of the equation by 15
You can call it a "number." To distinguish it from a variable expression, you can also call it a "constant."
No. In the variable x, alone, it is linear. In the variable y, alone, it is linear. But taken together, in x and y, you have a term which contains xy - that is, a term in which the powers of the unknowns add to 2. So the equation is not linear.
Multiply both sides of the equation by 1.5
To isolate a variable in an equation or inequality, you need to perform inverse operations to both sides. Start by eliminating any constants added or subtracted from the variable, followed by dividing or multiplying to remove coefficients. Ensure to maintain the equality or inequality by performing the same operations on both sides. Finally, simplify the expression to get the variable alone on one side.
