Solve for x: - 4X + 5 + 2 = - 126

-4x + 7=-126

-4y=-126-7

-4x=-133

x = 33.25

x = 133/4 or x = 33.25 decimal

Step-by-step 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
