Because you are taking away from the 15 dollars George has. You aren’t adding to it.
Answer:
x=-2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x+3)(2)−4=0
4x+12+−4=0(Distribute)
(4x)+(12+−4)=0(Combine Like Terms)
4x+8=0
4x+8=0
Step 2: Subtract 8 from both sides.
4x+8−8=0−8
4x=−8
Step 3: Divide both sides by 4.
4x/4 =-8/4
x=−2
f(a + 2)= 3a + 
substitute x = a + 2 into f(x)
f(a + 2) = 3(a + 2) +
= 3a + 6 +
= 3a +
