1) first slove for X ( 7y=15−<span>x) to solve this first subtract 15 from both sides -->
7y-15= -X ---> then multiply by -1 on both sides -----> -7y+15=x ( switch sides) so basically : </span>x=−7y+1<span>5
2) Then </span> Substitute x=-7y+15x=−7y+15 into 8x+4y=16 now solve steps below how to solve:
Start with the original equation ( 8x+4y=16)
Let x= -7y+15
<span>8(−7y+15)+4y=16 ----> simplify ----> −52y+120=16
Now solve for Y ( </span>−52y+120=1<span>6) steps:
</span>−52y=16−120 ( subtract 120 from both sides) & simplify by 16-120=−104
−52y=−104
now isolate Y divide both sides by -52 ----> y=2
Substitute y=2 into x=-7y+15
x= -7(2)+15
x=1
your final answer :
x=1
y=2
Factor and find commmon ones
25=1*5*5
33=1*3*11
GCF=1
(I am noticing that GCF=1 for many of your questions)

Explanation:</h3>
1. Earned income is said to be $35,000.
2. Base tax amount at that level is $4386.
3. The amount over $31850 is $35000-31850 = $3150
4. Line 3 is multiplied by 25%: $3150×0.25 = $787.50
5. The sum of lines 2 and 4 is $4386 +787.50 = $5173.50
6. This amount divided by 12 is ... $5173.50/12 ≈ $431.13
Answer:
54
Step-by-step explanation:
144 divided by 8 is 18
so that means that their hourly rate 18 pizzas per hour
so multiply 18 by 3 and get 54
