Its pretty simple all it is asking you to do is divided 126 by 7 which is 18 (the new bag) and the subtracting it by 3, which would give you 15. Hope I helped!

The solution to the system is (3,4):<br> 3x – 2y = 1<br> 4y = 7+3x<br> Pizz help mee
Marina86 [1]

Answer:

(3,4) is the solution of both equations.

Step-by-step explanation:

The given equations are :

3x – 2y = 1 ....(1)

4y = 7+3x

4y-3x = 7 .....(2)

Put x = 3 and y = 4 in equation (1).

3(3) – 2(4) = 9-8

= 1

So, (3,4) is the solution of the equation (1).

Again put x = 3 and y = 4 in equation (2).

4(4)-3(3) = 16-9

= 7

Hence, (3,4) is the solution of both equations.
