Answer:
x = -15 thus c: is your answer
Explanation:
Solve for x:
10 = (-2 x)/3
10 = (-2 x)/3 is equivalent to (-2 x)/3 = 10:
(-2 x)/3 = 10
Multiply both sides of (-2 x)/3 = 10 by -3/2:
(-3 (-2) x)/(2×3) = (-3)/2×10
(-3)/2×(-2)/3 = (-3 (-2))/(2×3):
(-3 (-2))/(2×3) x = (-3)/2×10
(-3)/2×10 = (-3×10)/2:
(-3 (-2) x)/(2×3) = (-3×10)/2
(-3)/3 = (3 (-1))/3 = -1:
(-2-1 x)/2 = (-3×10)/2
(-2)/2 = (2 (-1))/2 = -1:
--1 x = (-3×10)/2
(-1)^2 = 1:
x = (-3×10)/2
10/2 = (2×5)/2 = 5:
x = -35
-3×5 = -15:
Answer: x = -15
