Answer:
5.5
Step-by-step explanation:
Given:
18 -7x = -20.5
We can find x by subtracting 18, then dividing by the coefficient of x. (This is known as a 2-step equation.)
-7x = -38.5 . . . . . subtract 18 from both sides
x = -38.5/-7 = 5.5 . . . . .divide by -7
The value of x is 5.5.
20 + x = 10
20 + -10 = 10
x = -10
