-3x-3y=3<br> 5x+y=-17 <br> Substitution <br> What does x and what does y equal

earnstyle [38]

Answer:

$x=-4\\\\y=3$

Step-by-step explanation:

Given Equations:

$-3x-3y=3$ Equation:1

$5x+y=-17$ Equation:2

Solving Equation:2 for the value of 'y'

$5x+y=-17$

Subtracting '5x' both sides:

$y=-17-5x$ Equation:3

Using substitution method: Put the value of 'y' in equation:1

$-3x-3y=3$

$-3x-3(-17-5x)=3\\\\-3x-3(-17)-3(-5x)=3\\\\-3x+51+15x=3\\\\12x+51=3\\\\$

Subtracting '51' both sides:

$12x=3-51\\\\12x=-48\\\\x=-48/12\\\\x=-4$

Putting the value of 'x' in equation:3

$y=-17-5x$

$y=-17-5(-4)\\\\y=-17+20\\\\y=3$

The values of 'x' and 'y' are:

$x=-4\\\\y=3$
