Question

Solve for a.

5a−5−15=3a+6+4

Answer 1

Answer:

a = 15

Step-by-step explanation:

5a - 5 - 15 = 3a + 6 + 4     combine like terms

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

5a - 20 = 3a + 10       add 20 to both sides

5a = 3a + 30      subtract 3a from both sides

2a = 30       divide both sides by 2

a = 15
