Answer:

x=4

Step-by-step explanation:

I used cross multiplication

7+2x/3=5

7+2x/3=5/1

7+2x(1)=5(3)

7+2x=15

2x=15-7

2x=8

x=4

Answer:

x = 4

Step-by-step explanation:

The goal is to get x by itself.

1. Multiply both sides by 3 and you are left with:

7 + 2x = 15

2. Subtract 7 from both sides and you are left with:

2x = 8

3. Simplify by dividing each side by 2 and you are left with the answer:

x = 4
