Answer:
y= 1 and X=4
Step-by-step explanation:
8x +7y =39
8x +2y =34
elimination method(we multiply 8x+7y=39 or 8x + 2y= 34 by -1 to eliminate 8x)
lets multiply 8x+7y = 39 by - 1
-8x -7y = -39
8x +2y = 34
(8x-8x)+(2y-7y)= (-39+34)
0 + (-5y) = -5
-5y= -5......dividing both sides by -5
<em> y = 1</em>
8x +2y =34....... substituting y by 1
8x +2(1)= 34
8x + 2= 34
8x = 34-2
8x = 32.....dividing both sides by 8
<em>x = 4</em>
Lets check;
8x +2y = 34
8(4) +2(1) = 34
32 + 2 =34
<em>34 = 34</em>
8x + 7y = 39
8(4) + 7(1) = 39
32 + 7 =39
<em>39 = 39</em>
