9x + -3 = 5x + -15
Reorder the terms:
-3 + 9x = 5x + -15
Reorder the terms:
-3 + 9x = -15 + 5x
Solving
-3 + 9x = -15 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
-3 + 9x + -5x = -15 + 5x + -5x
Combine like terms:
9x + -5x = 4x
-3 + 4x = -15 + 5x + -5x
Combine like terms:
5x + -5x = 0
-3 + 4x = -15 + 0
-3 + 4x = -15
Add '3' to each side of the equation.
-3 + 3 + 4x = -15 + 3
Combine like terms: -3 + 3 = 0
0 + 4x = -15 + 3
4x = -15 + 3
Combine like terms: -15 + 3 = -12
4x = -12
Divide each side by '4'.
x = -3

Answer:
9
Step-by-step explanation:
7r+18=r²
r²-7r-18=0
factorizing
r²+2r-9r-18=0
r(r+2)-9(r+2=0
(r-9)(r+2)=0
r-9=0
r=9
check
(r²)=(9*9)=81
7r+18=7(9) + 8=81
