Answer:
S = -3
Step-by-step explanation:
4x -3 = -12
-12 + 18 = 6
6=6
Answer:
s = -3
Step-by-step explanation:
note: no matter what you do to an equation, as long as you repeat it on both sides the equation will still be true.
6 = 4s + 18
subtract 18 from both sides of the equation
6 - 18 = 4s + 18 - 18
6 - 18 = 4s
-12 = 4s
divide both sides of the equation by 4
-12/4 = 4s/4
-12/4 = s
-3 = s
