Question
Solve for xx:minus, left parenthesis, 10, x, plus, 10, right parenthesis, equals, 7, plus, 3, left parenthesis, minus, 10, x, minus, 8, right parenthesis−(10x+10)=7+3(−10x−8)
Solution
First, distribute the negative sign on the left side of the equation and the 3 on the right side of the equation:
-10x - 10 = 7 - 30x - 24
Simplify the equation:
-10x - 10 = -30x - 17
Next, add 30x to both sides of the equation to get all the x terms on one side:
20x - 10 = -17
Then, add 10 to both sides of the equation to isolate the x term:
20x = -7
Finally, divide both sides of the equation by 20 to solve for x:
x = -7/20
