Answer:
2a-9=2a-9
<em>Infinitely Many Solutions</em>
Step-by-step explanation:
2(a-8)+7=5(a+2)-3a-19
<em>Use Distributive Property</em>
2a-16+7=5a+10-3a-19
<em>Combine Like Terms</em>
2a-9=2a-9
<u><em>You don't have to go further unless it helps</em></u>
So you would do 5*2x +5*-8 +15=-15
Then simplify so it would be 10x + -40 + 15 = -15
Then add -40 and 15 together
Then it would be 10x + -25 = -15
Then add 25 to -25 and -15
So it would be 10x = 10
And then divide 10 from 10 with would be 1 so x = 1
