Write the equations and solve for the values of \( x \) and \( y \):

1. \( 7x + 3y = 22 \)
2. \( 4y = 20 \)

{ 7 x + 3 y = 22 4 y = 20 / : 4 ​ { 7 x + 3 ⋅ 5 = 22 y = 5 ​ { 7 x + 15 = 22 ∣ − 15 4 y = 20 ​
{ 7 x + 15 − 15 = 22 − 15 y = 5 ​ { 7 x = 7 / : 7 y = 5 ​ { x = 1 y = 5 ​

7x+3y=22 4y=20
4y=20 y=5
Substitute to first equation 7x+15=22 7x=7 x=1

The solutions to the equations are x = 1 and y = 5 . To find these values, we first solved the second equation for y and then substituted that value back into the first equation to solve for x . The final ordered pair representing the solution is ( 1 , 5 ) .
