PICTURE1: They are both 45
PICTURE2: 810
The answer is 45 because supplement means the sum of 180 so 180 divided by 4 is 45 and t=45
The expression that represents her weekly income is:
180 + 0.03w
If we multiply the bottom equation by 2 and move x to the right, it becomes:
4y = 2x-38
Now we can substitute it for the 4y in the top equation:
3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3
Then 4y = 2*3-38 => y = -8
So the solution is (3,-8)
