Answer:

7

Explanation:

5(x - 3) = 20

Distribute:

5x - 15 = 20

Get rid of constants to isolate variable on one side by adding 15, since the inverse operation of subtraction is addition:

5x - 15 = 20

+15 +15

5x = 35

Divide both sides by 5 to get variable alone since inverse operation of multiplication is division:

5x = 35

/5 /5

x = 7

Double check:

5(x - 3) = 20

Substitute:

5(7 - 3) = 20

Solve in parenthesis first:

5(4) = 20

20 = 20

x = 7 is correct.

Solving equations


\hspace{300}\above0.3

Let's solve the problem given to us today! The problem is :


5(x-3)=20

We need to find x. Follow these steps:

Distribute 5:


5x-15=20

Add 15 to both sides:


5x=35

Divide both sides by 5:


x=7

Therefore, x = 7.
