4x-2+15\left(-2x-1\right)=-10\left(3+2x\right)-3x
Multiply both sides of the equation by 5.
4x-2-30x-15=-10\left(3+2x\right)-3x
Use the distributive property to multiply 15 by -2x-1.
-26x-2-15=-10\left(3+2x\right)-3x
Combine 4x and -30x to get -26x.
-26x-17=-10\left(3+2x\right)-3x
Subtract 15 from -2 to get -17.
-26x-17=-30-20x-3x
Use the distributive property to multiply -10 by 3+2x.
-26x-17=-30-23x
Combine -20x and -3x to get -23x.
-26x-17+23x=-30
Add 23x to both sides.
-3x-17=-30
Combine -26x and 23x to get -3x.
-3x=-30+17
Add 17 to both sides.
-3x=-13
Add -30 and 17 to get -13.
x=\frac{-13}{-3}
Divide both sides by -3.
x=\frac{13}{3}
Fraction \frac{-13}{-3} can be simplified to \frac{13}{3} by removing the negative sign from both the numerator and the denominator.
