Question

(1) x-y=-1;3x-2y=12 by substitution method solve please​

Answer 1

Answer:

y=15 x =14

Step-by-step explanation:

x-y =-1------(1)

3x-2y =12---(2)

by equation (1) x = y-1 -----(3)

substituting equation (3)in (2)

3(y-1) -2y=12

3y-3-2y =12

y =12+3

y = 15

substituting y in equation (3)

x=15-1

x =14
