x-10=15
Add 10 to both sides
x=25
x=15
-9
16
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
Divide each side by -15 and x = - 6/15.
x - 15 = - 8 add 15 to both sides: x -15 + 15 = -8 + 15 simplify both sides: x = 7
15x = 45 Solve for x by dividing both sides by 15. 15/15 x = 45/15 Simplify. x = 3
Yes, if x10=y.
10 x 10 x 10 x 10 x10 x 10 x 10 =10,000,000
x2+x-15 = 0 Using the quadratic equation formula: x = 3.405124838 or x = -4.405124838
15
(4x+3)(x-5) = 0 x = -3/4 or x = 5
