Solve the system of equations by substitution.
y = 5x - 11
2x + 3y = 18

x=3 y=4

Step-by-step explanation:

y=5x-11

2x+3y=28

2x+3(5x-11)=18

2x+15x-33=18

         +33  +33

2x+15x=51

17x=51

51/17=3

x=3

Plug 3 in for x to get 4 for y

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
