Answer:
(4,-3)
Step-by-step explanation:
3x-15=-4x+13
7x=28
X=4
3x4-15=-3
Answer: b) (32,28)
Step-by-step explanation:
Let x be the number of polio individual doses and y be the number of each measles individual doses.
Then the number of polio vaccination = 44x
The number of measles vaccination multi-dose = 22x
According to the question,
Dividing 22 on equation (2) both sides, we gwt
Subtract (1) from (3), we get
Substitute x=32 in equation (1), we get
Hence, Dr. Potter gives 32 individual polio vaccination and 28 individual measles vaccinations .

If I were you, I would select the first equation to put in y=mx+b form so that you can substitute it in to the second one. What you do is you subtract the x from the left side and bring it over to the right and then you divide everything by 5. The y=mx+b equation is y=-1/5x-7. Then, you substitute this equation into the bottom one so you are now working only with x's. You should distribute and combine like terms. When you distribute and clean it up, at the end you should get 18/5x-14=8. You then add 14 to get 22 on the right side and then multiply that by the reciprocal of the fraction. When you multiply 22 by 5/18, you should get a reduced fraction of 55/9. You then substitute this value into either equation to get the y-value. You should get a y-value of -260/45. Your answer as an ordered pair should be (55/9,-260/45).
