Solve for a.5a−5−15=3a+6+4

Mathematics
1 answer:
taurus [48]3 years ago
5 0

Answer:

<h3>a = 15</h3>

Step-by-step explanation:

5a - 5 - 15 = 3a + 6 + 4     <em>combine like terms</em>

5a + (-5 - 15) = 3a + (6 + 4)

5a - 20 = 3a + 10       <em>add 20 to both sides</em>

5a = 3a + 30      <em>subtract 3a from both sides</em>

2a = 30       <em>divide both sides by 2</em>

a = 15
