Answer:
x = - 9 (negative 9)
Step-by-step explanation:
The x intercept is where y = 0. When y = 0, the point is on the x axis.
So use the equation and replace y with 0.
-2x + 1/2y = 18
-2x + 1/2(0) = 18
-2x + 0 = 18
-2x = 18
x = - 9
Check you answer by putting your answer for x into the equation. See if it does make y = 0
-2x + 1/2y = 18
-2(- 9) + 1/2y = 18
18 + 1/2y = 18
1/2y = 0 so y must also equal 0

Use a calculator to evaluate the left and right side separately.
4/3 = 24/30
1.333 = 0.8
The equation is false.
----------------------------------
Alternatively, you can cross multiply like so
4/3 = 24/30
4*30 = 3*24
120 = 72
Since that equation is false, it means that the original equation 4/3 = 24/30 is false.
