Answer: x = 17
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-243-(-9*(10+x))=0
-243 - (0 - 9 • (x + 10)) = 0
9x - 153 = 9 • (x - 17)
Equation at the end of step 3 : 9 • (x - 17) = 0 Step 4
Solve: x-17 = 0
Add 17 to both sides of the equation : x = 17
One solution was found :
x = 17
