Answer:
Solve for 's' using inverse operations;
4s + 3 = 9
Get rid of constants first.
By doing this, we subtract 3 from both sides because the inverse operation of addition is subtraction.
-3 -3
4s = 6
Isolate 's' by dividing 4 from both sides because the inverse operation of multiplication is division.
÷ 4 ÷ 4
s = 6/4 which equals 1.5 therefore the value of 's' to make this equation true is 1.5.
