-10 (-4x + 7) = 130
To solve this equation, we will use the distributive property to remove the parentheses
To solve this equation, we will use the distributive property to remove the parentheses. Let’s do it step by step:
-10(-4x + 7) = 130
First, distribute -10 to each term inside the parentheses:
(-10) * (-4x) + (-10) * 7 = 130
That gives us:
40x – 70 = 130
Next, we isolate the variable term by moving the constant term to the other side of the equation. We can do this by adding 70 to both sides:
40x – 70 + 70 = 130 + 70
Simplifying, we get:
40x = 200
Now, to find the value of x, we divide both sides of the equation by 40:
40x/40 = 200/40
Simplifying further:
x = 5
So, the solution to the equation is x = 5.
