How do you solve x plus 9y equals 9?
To solve for 2 unknown variables you need 2 independent equations. You have only 1.
How do you solve 2 equals x- one third y?
You can't. You need 2 equations to solve for 2 unknowns
How did the Babylonians solve quadratic equations?
1+1=2
How do you solve these equations?
Tell me the equations first.
Does this web site solve equations?
There are people who use this web site that can and will solve equations.
How can you use a graph to solve systems of equations?
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
What is the answer to solve by elimination x plus 2y equals 0?
The answer is that it cannot be done. To solve a set of equations in k variables (in this case, 2) you need at least two independent equations.
How do you solve trigonometric equations?
The answer depends on the nature of the equations.
How do you solve 3w plus 7 equals x?
You can't solve it - you only have one equation and two unknowns. You need 2 equations to solve this.
How do you solve linear equations by using elimination?
You multiply one or both equations by some constant (especially chosen for the next step), and add the two resulting equations together. Here is an example: (1) 5x + 2y = 7 (2) 2x + y = 3 Multiply equation (2) by -2; this factor was chosen to eliminate "y" from the resulting equations: (1) 5x + 2y = 7 (2) -2x -2y = -6 Add the two equations together: 3x = 1 Solve this for "x", then replace the result in any of the two original equations to solve for "y".
What is the solution of x plus y equals -2 and 2x plus 3y equals -9?
x + y = -2 2x + 3y = -9 You solve this by elimination - multiply both sides of first equation by 3, then subtract, solve for x, then substitute in any of the equations to solve for y 3x + 3y = -6 2x + 3y = -9 subtracting, x = 3 substituting into 1st equation, y = -2-3 = -5
How do you solve equations with fraction?
You solve equations with fractions the same way you solve other equations. You perform various arithmetic operations on both sides of the equals sign until you get the result you want.
