3x-\left(1-2-3x\right)=7
To find the opposite of 2+3x, find the opposite of each term.
3x-\left(-1-3x\right)=7
Subtract 2 from 1 to get -1.
3x-\left(-1\right)-\left(-3x\right)=7
To find the opposite of -1-3x, find the opposite of each term.
3x+1-\left(-3x\right)=7
The opposite of -1 is 1.
3x+1+3x=7
The opposite of -3x is 3x.
6x+1=7
Combine 3x and 3x to get 6x.
6x=7-1
Subtract 1 from both sides.
6x=6
Subtract 1 from 7 to get 6.
x=\frac{6}{6}
Divide both sides by 6.
x=1
Divide 6 by 6 to get 1.
