Question

Solve the inequality -4s + 12 < 60

Answer 1

-4s+12<60

Since 12 does not contain the variable to solve for, move it to the right-hand side of the inequality by subtracting 12 from both sides.
-4s<-12+60

Add 60 to -12 to get 48.
-4s<48

Divide each term in the inequality by -4. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.
-(4s)/(-4)>(48)/(-4)

Simplify the left-hand side of the inequality by canceling the common factors.
s>(48)/(-4)

Simplify the right-hand side of the inequality by simplifying each term.
s>-12

Answer 2

subtract 12 from both sides
-4s<48
divide by negative 4
s>12.
when you divide my a negative it flips

Answer 3

s>-12

Answer 4

oh yeah @fourme , forgot the negative.
