What are the steps for 2x+1=7
1 answer:
Answer:
<em>x = 3</em>
Step-by-step explanation:
Step 1:
Subtract 1 from both sides
2x + 1 = 7
2x + 1 - 1 = 7 - 1
<u>2x = 6</u>
(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
<u>x = 6 ÷ 2</u>
(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
<u>x = 3</u>
