Answer 1

x = 7

Explanation:

solve the equation in the photo

A.1.8

B.5

C.7

D. 11.7

x - 13 + 4x = 22

5x - 13 = 22

5x = 22 + 13

5x = 35

x = 35 : 5

x = 7

-----------------------------

check

7 - 13 + 4 × 7 = 22 (remember PEMDAS)

7 - 13 + 28 = 22

22 = 22

same value the answer is good

Answer 2

Answer: x = 7

First you want to combine like terms:

x - 13 + 4x = 22

5x - 13 = 22

Next you want to add 13 to both sides:

5x - 13 = 22

5x - 13 + 13 = 22 + 13

You then want to simplify the expression:

5x - 13 + 13 = 22 + 13

5x = 22 + 13

22 + 13 = 35

5x = 35

Then you want to divide both sides by the same factor:

5x = 35

5x / 5 = 35 / 5

Then simplify the expression:

x = 7.

Correct answer is x = 7
