Answer:
x = 133/4 or x = 33.25 decimal
Explanation:
Solve for x:
7 - 4 x = -126
Subtract 7 from both sides:
(7 - 7) - 4 x = -7 - 126
7 - 7 = 0:
-4 x = -7 - 126
-7 - 126 = -133:
-4 x = -133
Divide both sides of -4 x = -133 by -4:
(-4 x)/(-4) = (-133)/(-4)
(-4)/(-4) = 1:
x = (-133)/(-4)
Multiply numerator and denominator of (-133)/(-4) by -1:
Answer: x = 133/4
