Solution
1 Add 7 to both sides
2(3x+1)=13+7
2 Simplify 13+7 to 20
2(3x+1)=20
Divide both sides by 2
3x+1=20 / 2
Simplify 20 / 2 to 10
3x+1=10
Subtract 1 from both sides
3x=10−1
Simplify 10−1 to 9
3x=9
Divide both sides by 3
x=9 / 3
Simplify 9 / 3 to 3
x=3
1 Add 7 to both sides
2(3x+1)=13+7
2 Simplify 13+7 to 20
2(3x+1)=20
Divide both sides by 2
3x+1=20 / 2
Simplify 20 / 2 to 10
3x+1=10
Subtract 1 from both sides
3x=10−1
Simplify 10−1 to 9
3x=9
Divide both sides by 3
x=9 / 3
Simplify 9 / 3 to 3
x=3
