For part A Amy's estimate is inaccurate because when adding fractions they must have the same denominators. Amy probably made the mistake of adding 1/4 and 1/3 without changing the denominators first which gave her 1/7. If she were to do it correctly then she would've ended up with 7/12 as her answer.

My work:

1/4=3/12
1/3=4/12
4/12+3/12=7/12

I hope this helps and if I gave any false information I apologize in advance.

Solve the following simultaneous equations : with the help of steps<br>1. x + 2y = 1, 3x - y = 17​
IRISSAK [1]

Answer:

x = 5, y = -2

Step-by-step explanation:

<u>Given equations:</u>

  • x + 2y = 1
  • 3x - y = 17​

<u>From the first equation we get:</u>

  • x = 1 -2y

<u>Substitute x in the second equation, find y:</u>

  • 3x - y = 17
  • 3*(1-2y) - y = 17
  • 3 - 6y - y = 17
  • -7y = 17 - 3
  • -7y = 14
  • y = -14/7
  • y = -2

<u>Find x:</u>

  • x = 1 - 2y
  • x = 1 - 2*(-2)
  • x = 1 + 4
  • x = 5

Y=3/2x-1<br> -6x+4y=-4<br> Does this have no solution or infinitely many solutions please explain.
Aleks04 [339]

Answer:

infinitely many solutions

Step-by-step explanation:

Let's eliminate the fractional coefficient in the first equation by multiplying that equation by 4:

4y = 6x - 4

The second equation can be rewritten as 4y = 6x - 4, so the two equations are actually identical.  They have infinitely many solutions.
