1.2-x-\left(-0.8\right)=-2\left(0.9+x\right)
To find the opposite of x-0.8, find the opposite of each term.
1.2-x+0.8=-2\left(0.9+x\right)
The opposite of -0.8 is 0.8.
2-x=-2\left(0.9+x\right)
Add 1.2 and 0.8 to get 2.
2-x=-1.8-2x
Use the distributive property to multiply -2 by 0.9+x.
2-x+2x=-1.8
Add 2x to both sides.
2+x=-1.8
Combine -x and 2x to get x.
x=-1.8-2
Subtract 2 from both sides.
x=-3.8
Subtract 2 from -1.8 to get -3.8.
