Answer:2
Step-by-step explanation:
<span>Multiply
the 1st equation by 5 and multiply the 2nd equation by 2. This will
eliminate the x's when you add the two new equations together.
</span>
<span>A) −2x+3y=8
B) 5x+4y=10
So we multiply A) by 5 and B) by 2
</span><span>A) −10x+15y=40
B) 10x+8y=20
</span>
Adding the equations:
23y = 60
y =
