Answer:

x = 8

Explanation:

5(x + 3) – 12 = 43

Add 12 to each side

5(x + 3) – 12+12 = 43+12

5(x+3) =45

Divide each side by 5

5(x+3)/5 = 55/5

x+3 = 11

Subtract 3 from each side

x+3-3 = 11-3

x = 8

Answer:


x=8

Explanation:

We can solve this equation by isolating the variable x.

First let’s apply the distributive property:


5(x+3)-12=43\\5\cdot x + 5\cdot3 - 12=43\\5x + 15 - 12 = 43

Combine like terms:


5x + 3 = 43

Now we can subtract 3 from both sides:


5x + 3 - 3 = 43-3\\5x = 40

Divide both sides by 5:


5x/5 = 40/5\\x = 8

So
x=8.

Hope this helped!
