answer

x=6,y=14

Step-by-step explanation:

make -5x+5x=40 as equation (1)

4x+3y=24...... (2)

Find equation (3) from (1)

-5x+5y=40

-5x/-5=(40-5y)-5

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

Substitute (3) from (2)

4x+3y=24

4 (y-8)+3y=24

4y-32=24

4y=24+32

4y=56

y=14

find x from equation (3)

x=y-8

x=14-8

x=6
