Answer:
Step-by-step explanation:
This drawing illustrates the
equation: -3x – 7 = 5.
Since:
(-x + -x + -x) + (-1 + -1 + -1 + -1 + -1 + -1 + -1) =
(1 + 1 + 1 + 1 + 1) → (-3x) + (-7) = (5) →
-3x – 7 = 5.
To reduce the equation and find x:
[add 7 to both sides to isolate the constant term on the right side]
-3x – 7 + 7 = 5 + 7 →
-3x = 12 →
[divide both sides by -3 to cancel out the coefficient of -3 in -3x to get x]
-3x / -3 = 12 / -3 →
x = -4
