To find those equations we can do any multiplication or division of both sides of the equation:
Examples:
2x + 9 = -15 | · 2
4x + 18 = -30
2x + 9 = -15 | · (-1)
-2x - 9 = 15
2x + 9 = -15 | ÷ 2
x + 4.5 = -7.5
There is the same solution: x = -12.
Answer:
.5(4x+18)=-15 Half of 4 is 2 and half of 18 is nine
-15-9=2x Basically just flip the problem
2x+15=-9 Rearrange them again...
