**Answer:**

x=2

y=4

**Step-by-step explanation:**

x+5y=22

x= 22-5y

sub in 2

2x-3y=-8

2(22-5y) -3y =-8

44 - 10y -3y =-8

44+8 = 13y

52 =13y

y = 52/13

y= 4

sub in 1

x= 22-5×4

x= 22-20

x= 2

The two equations :-

- x+5y=22

- 2x-3y=-8

- Find the value of x & y by substitution method.

We have two equations,

- x + 5y = 22 ------(1)

- 2x - 3y = -8 ------(2)

Solving the first,

x + 5y = 22

➝ 5y = 22 - x

➝ y =

Putting in 2 equation,

2x - 3 × = -8

2x - = -8

2x - = -8

= -8

10x - 66 - 3x = -8 × 5

10x - 66 - 3x = -40

10x - 3x = -40 + 66

7x = 26

__x = 26/7__

**Putting in 1 equation, **

x + 5y = 22

x + 5 × 26/7 = 22

x + 130/7 = 22

x = 22 - 130/7

x = 154 - 130 /7

__x = 24/7__

x+5y=22

➝ 24/7 + 5 × 26/7 = 22

➝ 24/7 + 130/7 = 22

➝ 154/7 = 22

➝ __22 = 22__
