Graph the solution of the inequality: 4/9x - 10 > x/3 - 12

Estimation of 492.6 divided by 48

3x+6y=12 x + 5y=10 x = 10 - 5y 3 (10 - 5y) + 6y=12 30-15y+6y=12 30-9y = 12 -9y=-18 y=2 Joey has to solve the system of equations using substitution. He had completed the work shown. What should be his next step
