Answer:
4. Multiply both sides by -2 => x - 7 = -36, Add 7 to both sides -> x = -29
5. Add 12 to both sides => 28 = 1/4x, then multiply both sides by 4 => 112
x = 112
7. Multiply both sides by 3 => 5x - 2 = 63, add 2 to both sides => 5x = 65,
Divide both sides by 5 -> x = 13
10. Multiply both sides by 6 => 132 = 3x - 6, Add 6 to both sides => 138 = 3x,
Divide both sides by 3 => x = 46
Step-by-step explanation:
Where is the picture???????
The correct answer is: x=9
4(1-x)+2=-3(x+1 )
-4x +3x = -3 -6
-x=-9
x=9
11.9+7m=10m (subtract 7m from both sides)
-7m -7m
11.9/3=3/3m (divide both sides by 3 to find m)
3.96666= m
