Absolute value
|x +4| < 1

a.) -5 < y < -3
b.) -3 < y < 5
c.) -4 < y < 1
d.) 1 < y < 4

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
