Answer:
2
Step-by-step explanation:
1 Subtract 66 from both sides.
2x=10-6
2x=10−6
2 Simplify 10-610−6 to 44.
2x=4
2x=4
3 Divide both sides by 22.
x=\frac{4}{2}
x=
2
4
4 Simplify \frac{4}{2}
2
4
to 22.
x=2
x=2
Done
2x+22=18
We move all terms to the left:
2x+22-(18)=0
We add all the numbers together, and all the variables
2x+4=0
We move all terms containing x to the left, all other terms to the right
2x=-4
x=-4/2
x=-2
