Answer:
a= 40
Step-by-step explanation:
-5a + 7.5a - 25 = 53.2 + 21.8
add like terms on both sides: 2.5a - 25 = 75
add 25 on both sides: 2.5a = 100
divide both sides by 2.5: a = 40
Answer:
a = 40
Step-by-step explanation:
-5a + 15/2a - 25 = 53.2 + 21.8: Add 25 to Isolate variable
-5a + 15/2a = 53.2 + 21.8 + 25: Combine Like Terms and create simmilar terms
-10/2a + 15/2a = 100: CLM again
5/2a = 100: multiply both sides by inverse of 5/2 to isolate variable
a = 40
