Question 424739
1+3x<22

Since 1 does not contain the variable to solve for, move it to the right-hand side of the inequality by subtracting 1 from both sides.
3x<-1+22

Add 22 to -1 to get 21.
3x<21

Divide each term in the inequality by 3.
(3x)/(3)<(21)/(3)

Simplify the left-hand side of the inequality by canceling the common terms.
x<(21)/(3)

Simplify the right-hand side of the inequality by simplifying each term.
x<7
