Answer:
x = 3
y = 2
Step-by-step explanation:
3x + 2y = 12
-2x + 3y = 5 to find the solution we will use elimination method and for that, multiply second equation with 3 and the first equation with 2
<em>2 * 3x + 2y = 12</em>
<em>6x + 4y = 24</em>
<u>3 * -2x + 3y = 5</u>
<u>-6x + 9y = 15</u> now find the sum of both equation:
<em>6x + 4y </em><u>-6x + 9y</u> = 24 + 15 add like terms
13y = 39 divide both sides by 13
y = 3 now that we found the value of y we can use this to calculate the value of x
3x + 2y = 12 replace y with 3
3x + 2*2 = 12
3x + 4 = 12 subtract 4 from both sides
3x = 9 divide both sides by 3
x = 3
