Answer:
that's the answer
Step-by-step explanation:
7 (y+3) - 2 (x+2)=14
7y+21 - 2x + 4=14
7y - 2x = - 11 -----------------(1)
4 (y-2)+3 (x-3)=2
4y-8+3x - 9= 2
4y + 3x = 19 -------------------(2)
multiplying eq 1 with 3 and 2 with 2
21y- 6x=-33
8y+6x = 38
--------------------
29y = 5
y= 5/29
x= 9/24

Answer:
y = 3/7 + 2/7 x
Step-by-step explanation:
7(y+3) - 2(x+2) = 14
7y+21 - 2x+4 = 14
7y-2x = 14-21-4
7y-2x = -11
y-x= -11 by 7-2
y-x=-11 by 5
I think this was the correct answer in my way...
or
7y +21-2x +4 = 14
7y+17-2x=14
7y = 14-17+2x
7y=-3+2x
now divide both sides by 7
y = 3/7 + 2/7 x
