a) 1/2x + x = -10
b) 3/2 x = -10 ————– add x variables together
c) 2/3(3/2x) = 2/3(-10) ——- multiply both sides by reciprocal of x coefficient
d) x = -20/3 ———— simplify, this is the answer

Add the x’s to get one and a half x.
11/2 x= -10
move all the numbers to the right, leaving the single x on the left.
x = -10 divided by one and a half (1 1/2)
invert the division to turn it into a multiplicantion prob
x = -10 times 2 divided by 3
x = – 6.66 (minus 6.66)

multiply both sides by 2.
2 (-10) = 2(1/2x + x)
-20 = x + 2x
Reduce:
-20 = 3x
Divide each side by 3.
-20/3 = x
or
x= – 6.66667
