-10 (-4x + 7) = 130
To solve the equation -10 (-4x + 7) = 130, we will simplify and solve for x
To solve the equation -10 (-4x + 7) = 130, we will simplify and solve for x.
Step 1: Distribute the -10 to the terms inside the parentheses:
-10 * -4x + (-10) * 7 = 130
40x – 70 = 130
Step 2: Add 70 to both sides of the equation to isolate the term with x:
40x – 70 + 70 = 130 + 70
40x = 200
Step 3: Divide both sides of the equation by 40 to solve for x:
40x / 40 = 200 / 40
x = 5
Therefore, the solution to the equation -10 (-4x + 7) = 130 is x = 5.
