Question

What is - (3x - 14) + 4 (5x + 18) = 122

Answer 1

`x=2(2)/(17)`

Explanation:

Do the distributive property.
`-3x+14+20x+72=122`

Reorder the equation to make it easier to combine common terms.
`-3x+20x+14+72=122`

Combine common terms.
`17x+86=122`

Subtract 86 from both sides of the equation to isolate the 17x.
`17x=36`

Divide both sides of the equation by 17 to isolate the x.
`x`≈
`2.118` or
`x=2(2)/(17)`
