2x+2-3x-5=2x-7
To find the opposite of 3x+5, find the opposite of each term.
-x+2-5=2x-7
Combine 2x and -3x to get -x.
-x-3=2x-7
Subtract 5 from 2 to get -3.
-x-3-2x=-7
Subtract 2x from both sides.
-3x-3=-7
Combine -x and -2x to get -3x.
-3x=-7+3
Add 3 to both sides.
-3x=-4
Add -7 and 3 to get -4.
x=\frac{-4}{-3}
Divide both sides by -3.
x=\frac{4}{3}
Fraction \frac{-4}{-3} can be simplified to \frac{4}{3} by removing the negative sign from both the numerator and the denominator.
