Answer:
x = (-9)/2 or decimal x = -4.5
Explanation:
Solve for x:
4 x + 18 = 0
Subtract 18 from both sides:
4 x + (18 - 18) = -18
18 - 18 = 0:
4 x = -18
Divide both sides of 4 x = -18 by 4:
(4 x)/4 = (-18)/4
4/4 = 1:
x = (-18)/4
The gcd of 18 and 4 is 2, so (-18)/4 = (-(2×9))/(2×2) = 2/2×(-9)/2 = (-9)/2:
Answer: x = (-9)/2
