Question

-9x+13=-29-12x como se hace

Answer 1

`x = -14`

Explanation:

We can solve for the variable x in the equation:

`-9x+13=-29-12x`

with the following steps:

↓ add 12x to both sides

`-9x \: \bold{+ \: 12x} + 13 = -29 -12x \: \bold{+\: 12x}`

↓ combine like terms (terms with x's)

`3x + 13 = -29 + 0`

↓ rewrite without added 0

`3x + 13 = -29`

↓ subtract 13 from both sides

`3x + 13 \: \bold{-\:13} = -29 \: \bold{-\:13}`

↓ execute the subtraction

`3x = -42`

↓ dividing both sides by 3

`(3x)/(3) = (-42)/(3)`

↓ execute the division

`\boxed{x = -14}`
