2x+1=4x+9

2x - 4x = 9 - 1

-2x = 8

x = 8/ -2

x = - 4

Usuário anônimo: Simplifying
2x + 1 = 4x + 9

Reorder the terms:
1 + 2x = 4x + 9

Reorder the terms:
1 + 2x = 9 + 4x

Solving
1 + 2x = 9 + 4x

Solving for variable 'x'.

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

Add '-4x' to each side of the equation.
1 + 2x + -4x = 9 + 4x + -4x

Combine like terms: 2x + -4x = -2x
1 + -2x = 9 + 4x + -4x

Combine like terms: 4x + -4x = 0
1 + -2x = 9 + 0
1 + -2x = 9

Add '-1' to each side of the equation.
1 + -1 + -2x = 9 + -1
