Solve 4(a + 2) + 9 = 5
2 answers:
4(a + 2) + 9 = 5
to solve this problem lets solve this step by step
Step 1 - lets solve this part of problem 4(a + 2 )
by using distributive property we get,
4a + 8 + 9 = 5
Step 2 - adding the like terms
4a + 17 = 5
Step 3 - subtracting 17 from both sides
4a + 17 - 17 = 5 - 17
4a = -12
Step 4 - dividing both sides by 4
a = -3
So our final answer is a = -3
Hope this helps you :)

The charges for mowing lawns are $5 per hour and charges for walking dogs are $3 per hour.
Step-by-step explanation:
Let,
x be the charge per hour for mowing lawns
y be the charge per hour for walking dogs
According to given statement;
10x+4y=62 Eqn 1
8x+5y=55 Eqn 2
Multiplying Eqn 1 by 5
Multiplying Eqn 2 by 4
Subtracting Eqn 4 from Eqn 3
Dividing both sides by 18
Putting in Eqn 1
Dividing both sides by 4
The charges for mowing lawns are $5 per hour and charges for walking dogs are $3 per hour.
