To solve for x, first isolate the variable by performing the necessary operations.
-20 = -5 + 3x
Add 5 to both sides of the equation:
-20 + 5 = -5 + 5 + 3x
-15 = 3x
Divide both sides by 3 to isolate x:
-15 / 3 = 3x / 3
-5 = x
Therefore, x = -5.
Solve for x .
−20 = −5 + 3x (1 point)

Solve for x . 20 =5 − 3/8x (1 point)
To solve for x, first isolate the variable by performing the necessary operations.
20 = 5 - (3/8)x
Subtract 5 from both sides of the equation:
20 - 5 = 5 - 5 - (3/8)x
15 = (-3/8)x
To solve for x, multiply both sides by the reciprocal of -3/8, which is -8/3:
(15)*(-8/3) = (-3/8)*(-8/3)x
-40 = x
Therefore, x = -40.
20 = 5 - (3/8)x
Subtract 5 from both sides of the equation:
20 - 5 = 5 - 5 - (3/8)x
15 = (-3/8)x
To solve for x, multiply both sides by the reciprocal of -3/8, which is -8/3:
(15)*(-8/3) = (-3/8)*(-8/3)x
-40 = x
Therefore, x = -40.
