Solving for Single Variable
Solve for x:
2x = 14
x = 7
Manipulate the equation so that one side is zero:
x2 = 9
x2 - 9 = 0
Solve for y:
4y + 15 = 35
y = 5
Manipulate the equation so that one side is zero:
9y2 - 5 = 4y2 + 15
5y2 - 20 = 0
Solve for z:
6z + 12 = 3z + 24
Manipulate the equation so that one side is zero:
14z2 + 6z + 2 = 11z2 + 5z + 5
3z2 + z - 3 = 0
