What are the steps for 2x+1=7

x = 3

Step-by-step explanation:

Step 1:

Subtract 1 from both sides

2x + 1 = 7

2x + 1 - 1 = 7 - 1

2x = 6

(1 - 1 will cancel itself out on the side with the variable.)

Step 2:

Divide both sides by 2

2x = 6

2x ÷ 2 = 6 ÷ 2

x = 6 ÷ 2

(2 divide by 2, will cancel itself out on the side with the variable.)

Step 3:

Solve for x

6 ÷ 2 = 3

x = 6 ÷ 2 = 3

x = 3

i think the length is 12 and the width is 17
