Which is the answer and how did you solve it?

1 answer:

3 0

Its pretty simple

9x-7y = 22
x + 3y = -24

(9x-7y = 22)
-9(x + 3y = -24)
= -9x -27y = 216
+ 9x-7y = 22
= -34y = 238
= / -34 = 238/-34
y = -7

now plug -7 in one of the equation
x + 3(-7) = -24
x -21 = -24
+21. +21
x = -3

so answer is x = -3 and y = -7

Okay so she had 67 homework problems and she only finished 25
she has 7 pages to complete and on each page the same number of problems

So we can use subtraction and division

(67 - 25) : 7 =
42 : 7 =
6
So there are 6 problems on each page :)
