## Can you solve an equation for two variables at the same time?

Divide both sides of the equation to “solve for x.” Once you have the x term (or whichever variable you are using) on one side of the equation, divide both sides of the equation to get the variable alone. For example: 4x = 8 – 2y.

How can we solve simultaneously?

Solving Systems of Equations (Simultaneous Equations)

1. Multiply one or both equations by some number(s) to make the number in front of one of the letters (unknowns) the same or exactly the opposite in each equation.
2. Add or subtract the two equations to eliminate one letter.
3. Solve for the remaining unknown.

How do you solve a x2 + bx + c = 0?

All equations of the form a x 2 + b x + c = 0 can be solved using the quadratic formula: 2 a − b ± b 2 − 4 a c ​ ​. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. Add 5 to both sides of the equation. Add 5 to both sides of the equation. Subtracting -5 from itself leaves 0.
