Answer:
I will assume that "first number is 6 less than 4 times a number" is meant to say something like "first number is 6 less than 4 times <u>the middle</u> number." As written, it offers no information. "first number is 6 less than 4 times a number" could be almost anything. If this can be clarified, consider the following process for solving the question.
Step-by-step explanation:
Three consecutive numbers: X, Y, and Z
We can rewite this as:
X = X
Y = X+1
Z = X+2
1) X = 4[?????] - 6 [Need some clarification about the "number"]
2) Z = 3X + 7 [Substitute the value for Z from above]
X+2 = 3X+7
2X = -5
And so on.
Answer:
Step-by-step explanation:
It is necessary to find the factors and solve them using their expressions in order to solve this problem.
<h3>20x+12y-28</h3>
7*4=28
3*4=12
5*4=20
Rewrite the problem down.
5*4x+3*4y+7*4
Solve.
Common term of 4.
<u>4(5x+3y-7)</u>
- <u>Therefore, the final answer is 4(5x+3y-7).</u>
<u></u>
I hope this helps you! Let me know if my answer is wrong or not.
well, the only exclusion I can see is that x ≠ 2, because if "x" ever becomes 2, the denominator goes to 0 and the fraction goes poof.
I'm not completely positive but I think it's C
