Question

Solve the equation 7=4s+19

Answer 1

7=4s+19
-12=4s
-3=s
that's the answer

Answer 2

Isolate the s. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

Subtract 19 from both sides

7 (-19) = 4s + 19 (-19)

7 - 19 = 4s

-12 = 4s

Isolate the s. Divide 4 from both sides

-12/4 = 4s/4

s = -12/4

s = -3

-3 is your answer for s
