Answer:

x=2 1/4

Step-by-step explanation:

Let's swap it around so its 1/3(8x+3)=7

Now you multiply both sides by 3 to make it 1(8x+3)=21

That means its 8x+3= 21

Subtract both sides by 3 to get rid of it

Now you have 8x=18

Which equals to x= 18/8

Which equals 2 1/4

The answer is 9/4 or 2 1/4

You multiply the parentheses by 1/3

7 = 8/3x +1

Then multiply both sides by 3

21 = 8x+3

Move terms

-8x= 3-21

Calculate

-8= -18

Divide both sides by -8

x= 9/4 or 2 1/4
