Answer:
Maya messed up on Step 1, David messed up on Step 2
Step-by-step explanation:
Maya:
Step 1 should distribute to 5x - 15 = 12
David:
Step 2 should be 3x - 2x = -2 - 3 after you combine like terms
1,068 is your answer. There will be 356 in each shipment because 1,424 divided by 4 is 356. And 356 times 3 is 1,068.
P and q both equal 16. This is because, 25 - 9 = 16.
5*(7x + 5y = 29)
<u>+ 21x - 25y = -33
</u>
35x + 25y = 145
<u>+ 21x - 25y = -33</u>
56 x + 0y = 112
56x = 112
x = 2
Plug the x back in to the original equation to solve for y.
7x + 5y = 29
7(2) + 5y = 29
14 + 5y = 29
5y = 15
y = 3
21x - 25y = -33
21(2) - 25y = -33
42 - 25y = -33
-25y = -75
y = 3
x = 2 and y = 3
