Question

How do u solve by substitution
2x=3y
x+2y=7

Answer 1

2x=3y = x=3y/2, sub in for x in x+2y=7

Answer 2

thanks

Answer 3

2x=3y
x=(3y)/2

Substitute into:

x+2y=7
(3y)/2+2y=7
Multiply the above equation by 2 to get:
3y+4y=147y=14
y=2

Now substitute 2 for y in the equation: 2x=3y
2x=(3) (2)=6
x=3

Therefore, x=3 and y=2
