Y = 3x + 15<br> 3x + 3y = 9

Zina [86]

Answer:

$\Large\boxed{x=-3}$ $\Large\boxed{y=6}$

Step-by-step explanation:

<u>Given the system of equations</u>

$1)~y=3x+15$

$2)~3x+3y=9$

<u>Divide 3 on both sides of the 2) equation</u>

$3x+3y=9$

$3x\div3+3y\div3=9\div3$

$x+y=3$

<u>Current system</u>

$1)~y=3x+15$

$2)~x+y=3$

<u>Substitute 1) equation into the 2) equation</u>

$x+(3x+15)=3$

<u>Combine like terms</u>

$x+3x+15=3$

$4x+15=3$

<u>Subtract 15 on both sides</u>

$4x+15-15=3-15$

$4x=-12$

<u>Divide 4 on both sides</u>

$4x\div4=-12\div4$

$\Large\boxed{x=-3}$

<u>Substitute the x value into one of the equations to find the y value</u>

$y=3x+15$

$y=3(-3)+15$

$y=-9+15$

$\Large\boxed{y=6}$

Hope this helps!! :)
