Solve the equation. Isolate the variable, x.
Note the equal sign, what you do to one side, you do to the other.
First, subtract 8 and 10x from both sides:
2x (-10x) + 8 (-8) = 12 (-8) + 10x (-10x)
2x - 10x = 12 - 8
Simplify. Combine like terms:
(2x - 10x) = (12 - 8)
-8x = 4
Isolate the variable, x. Divide -8 from both sides:
(-8x)/-8 = (4)/-8
x = -(4/8)
Simplify:
x = -1/2
-1/2 is your answer for x.

Answer:
38 students
Step-by-step explanation:
because 19% of 205 is 38.95, but not fully 39 students, so about 38 students
Answer:
40° and 140° (with x = -10)
Step-by-step explanation:
Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180
