Question

solve the following by using substitution method
2x = 20 + 3y, y=(x-13)/2​

Answer 1

Answer:

2x=20+3y

y=x-13/2.

Step-by-step explanation:

Simplify the second eqn:

x=2y+13

Substitute this into the second eqn

2(2y+13) =20 + 3y

4y + 26= 20+3y

4y-3y = 20-26

1y= -6

y= -6/1

y=-6

Substitute this of x:

x=2y+13

x=2(-6) +13

x= -12 + 13

x= 1
