2x-5y=-28 find the value of y when x equals -19
nydimaria [60]
<h3>Question:</h3>

2x-5y=-28 find the value of y when x equals -19

<h3>Answer:</h3>

Y = - 2

<h3>Step-by-step explanation:</h3>

First you plug in -19 where x is 2(-19)-5y = -28

Remove parentheses               -2 · 19-5y= -28

Multiply -2 by 19                       -38-5y= -28

Add 38 to both sides               -5y = 10

Divide both sides by -5            [tex]\frac{-5y}{-5} =\frac{10}{-5}[/tex

you will get -2 which is the answer.


Hope this helped!
