Answer:
2a - b = 5
Step-by-step explanation:
4a - 2b = 10
take out the highest common factor of the left side
2(2a - b) = 10
divide both sides by two
2a - b = 10/2
2a - b = 5
Answer:
f(9) = 42
Step-by-step explanation:
f(9) = (-9)*2 + 5*9 +15
= -18 + 45 + 15
= 42
12A + 2 + A - 1 = a + 12a + 1 = 13a + 1
