Question

someone please help me!!!! step by step instructions

Answer 1

8x+3=13+x
8x-x=13-3 (you put the x on the right to the left side it becomes negative, as well as the 3 on the other side. The goal is to isolate the x's)
7x=10
x=10÷7
x=10/7 or about 1.43

Answer 2

Answer:

10/7 or we could write it as 1 3/7

Step-by-step explanation:

8x + 3 = `13 + x

Subtract x from both sides

8x - x + 3 = 13 + x - x

7x + 3 = 13

Subtract  3 to both sides

7x + 3 - 3 = 13 - 3

7x = 10

Divide both sides by 7

7x/7 = 10/7

x = 10/7
