Answer:
5/12
Step-by-step explanation:
i just looked it up...
Equivalents fractions for 7/4:
7/4, 14/8, 21/12, 28/16, 35/20, 42/24, 49/28, 56/32, 63/36, 70/40, and so on ...
Example:
7/4 * 2/2 = 14/8
7/4 * 3/3 = 21/12
7/4 * 4/4 = 28/16
7/4 * 5/5 = 35/20
7/4 * 6/6 = 42/24 and so on.......
8x = 2y + 5
3x = y + 7
We will use the second equation to substitute in the first one. Here's how to do it:
3x = y + 7
y = 3x - 7 (now substitute this in the first equation)
8x = 2y + 5
8x = 2(3x - 7) + 5
8x = 6x - 14 + 5
8x = 6x - 9
6x - 9 = 8x
6x - 8x = 9
-2x = 9
x = -9/2 (this is the first coordinate, now we need to find y)
We use the second equation again:
3x = y + 7
y + 7 = 3x
y + 7 = 3(-9/2)
y + 7 = -27/2
y = -27/2 - 7
y = -27/2 - 14/2
y = -41/2 (this is the second coordinate)
This means that the solution set is the second option: <span>{(-9/2, -41/2)}</span>

Answer= 11. Two negatives equals a positive so you add them together.
