Question

2x-3y/4=3,5x=2y+7 solve by subsitution method​

Answer 1

Step-by-step explanation:

1)2x-3y/4=3

=y=3-2x*4/3

2)5x=2y+7

=x=2+7/5

Answer 2

Answer:

x=45/19    y=46/19

Step-by-step explanation:

(2x-3y)/4=3             5x=2y+7 → (2)

2x-3y=12

2x=12-3y

x=6 -3 y/2 → (1)

Substitute (1) in (2)

5(6-3y/2)=2y+7

30 - 15y/2 =2y + 7

23=19y/2

19y=46

y=46/19

From (1)

x=6 -3y/2

x=6 - (3×46/2×19)

x=6- 69/19

x=45/19
