Question

Solve the equation -5(x - 7) = 75 using square root.

a) x = -5
b) x = -14
c) x = 10
d) x = -10

Answer 1

To solve the equation -5(x - 7) = 75 using square root, distribute -5, subtract 35, and divide by -5 to find x = -8.

Step-by-step explanation:

To solve the equation -5(x - 7) = 75 using square root, we need to isolate the variable x. Start by distributing the -5 to the terms inside the parentheses:

-5x + 35 = 75

Next, subtract 35 from both sides:

-5x = 40

Finally, divide both sides by -5 to solve for x:

x = -8

So the correct answer is Option e) x = -8.
