Answer:
sameeeeeeeeeeeeeeeee but with school lol
have a good day :)
Step-by-step explanation:
2)
3x + y = 9 is equivalent to -15x - 5y = -45 by multiplying both sides by -5
<u>
</u> -15x - 5y = -45<u>
</u><u>+ </u><u>4x + 5y = 23</u>
-11x + 0y = -22
<u>
</u>-11x = -22
<em>x = 2</em>
3(2) + y = 9
6 + y = 9
<em>y = 3
</em>4)<em>
</em>2x + y = 17 is equivalent to -6x - 3y = -51 by multiplying both sides by -3
<em>
</em> 4x + 3y = 37
<u>+ (-6x - 3y = -51)
</u> -2x + 0y = -14
-2x = -14
<em>x = 7</em>
4(7) + 3y = 37
28 + 3y = 37
3y = 9
<em>y = 3</em><u>
</u>6)
x + 2y = 18 is equivalent to -10x - 20y = -180 by multiplying both sides by -10
10x - 3y = 19
<u>+ (-10x - 20y = -180)</u>
0x - 23y = -161
-23y = -161
<em>y = 7</em>
10x - 3(7) = 19
10x - 21 = 19
10x = 40
<em>x = 4
</em>
I hope this helped ^_^
