Answer:
- x = 3
- y = 4.
- There are infinite solutions. I'll just give you this solution.
Step-by-step explanation:
<u>Given equation:</u>
<u>Solve for variables:</u>
- 7 - x = y
- 7 - 3 = 4
- 7 - y = x
- 7 - 4 = 3.
<u>Answers:</u>
Divide both sides by -12
X=72/-12 now let's simplify 72/-12 = -72/12 so x= -72/12 simplify 72/12= 6
X= -6
Answer:
x<3
Step-by-step explanation:
3x - 4 < 17 - 4x
So, the -4 shall cross to the other side and replace the -4x which will now take the place of where the -4 used to be and the signs of both digits will change to a positive (+)
Remember the inequality sign (<) shall not change
so now the equation shall appear like this;
3x + 4x < 17 + 4
add both sides and it will appear like this;
7x < 21
simplify both sides by 7 and you'll get
x < 3
Answer :
Should be this I’m not sure though
Step-by-step explanation:
Answer:
5 DVD's
Step-by-step explanation:
So Basically It means the 25$ a month Plan is the same if you pay
5 DVD's
Ok each DVD costs 3$ and if you buy 5 of them you just bought 15 bucks worth of DVD's plus the membership which is 10$ in which the equation is
3(x)+10=25
X=5 by the way
So Basically it means if you Buy 5 DVD's plus the member ship thats the same money as the 25$ a month deal for unlimated DVD's
Simplified version: 5 DVD's
