X + 5y = 28<br> - x - 2y = -13
bazaltina [42]

Answer:

x=3

y=5

Step-by-step explanation:

x+5y=28 (i)

-x-2y=-13. (ii)

add equation 2 from equation 1

x+5y=28

-x-2y=-13

3y=15

y=5

put the value of y in equation 1

x+5y=28

x+5*5=28

x+25=28

x=28-25

x=3

What's the answer to this equation?
Serggg [28]
The answer is 5b²/6c

Ok so you just have to simplify
15/18 = 5/6 (cause 3*5=15 and 3*6=18)

Then you do as the picture above says.
