Answer 9

4x + 1 = 2x + 7 --- subtract 2x from both sides
4x - 2x + 1 = 7 --- subtract 1 from both sides
4x - 2x = 7 - 1 -- combine like terms
2x = 6 -- divide by 2
x = 3

Answer 10

Simplifying
4x + 1 = 2x + 7

Reorder the terms:
1 + 4x = 2x + 7

Reorder the terms:
1 + 4x = 7 + 2x

Solving
1 + 4x = 7 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.
1 + 4x + -2x = 7 + 2x + -2x

Combine like terms: 4x + -2x = 2x
1 + 2x = 7 + 2x + -2x

Combine like terms: 2x + -2x = 0
1 + 2x = 7 + 0
1 + 2x = 7

Add '-1' to each side of the equation.
1 + -1 + 2x = 7 + -1

Combine like terms: 1 + -1 = 0
0 + 2x = 7 + -1
2x = 7 + -1

Combine like terms: 7 + -1 = 6
2x = 6

Divide each side by '2'.
x = 3

Simplifying
x = 3
