4\left(x+1\right)-\left(1-3x\right)=10x+2
Multiply both sides of the equation by 2.
4x+4-\left(1-3x\right)=10x+2
Use the distributive property to multiply 4 by x+1.
4x+4-1-\left(-3x\right)=10x+2
To find the opposite of 1-3x, find the opposite of each term.
4x+4-1+3x=10x+2
The opposite of -3x is 3x.
4x+3+3x=10x+2
Subtract 1 from 4 to get 3.
7x+3=10x+2
Combine 4x and 3x to get 7x.
7x+3-10x=2
Subtract 10x from both sides.
-3x+3=2
Combine 7x and -10x to get -3x.
-3x=2-3
Subtract 3 from both sides.
-3x=-1
Subtract 3 from 2 to get -1.
x=\frac{-1}{-3}
Divide both sides by -3.
x=\frac{1}{3}
Fraction \frac{-1}{-3} can be simplified to \frac{1}{3} by removing the negative sign from both the numerator and the denominator.
