Question

How do you solve 13+4x=1-x

Answer 1

Simplifying 13 + 4x = 1 + -1x
Solving 13 + 4x = 1 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.13 + 4x + x = 1 + -1x + x
Combine like terms: 4x + x = 5x 13 + 5x = 1 + -1x + x
Combine like terms: -1x + x = 0 13 + 5x = 1 + 0 13 + 5x = 1
Add '-13' to each side of the equation. 13 + -13 + 5x = 1 + -13
Combine like terms: 13 + -13 = 0 0 + 5x = 1 + -13 5x = 1 + -13
Combine like terms: 1 + -13 = -12 5x = -12 Divide each side by '5'. x = -2.4 Simplifying x = -2.4

Answer 2

13+4x=1-x
4x=-12-x (minus 13 from each side)
5x=-12 (add x to each side)
You divide -12 by 5x
-12÷5x=2
`(2)/(5)`⇒2.4
x=2.4
