Answer:
5
Step-by-step explanation:
4(x+3) is 4x+12
2x+22=4x+12
-2x from both sides
get 22=2x+12
-12 from both sides
get 10=2x
divide by 2 to both sides
get 5
Answer:
x+3x+5=101 (Option C).
Step-by-step explanation:
This question requires to be solved using the supposition method.
Let Aylen's savings be $x. Therefore, Rich's savings would be $(3x+5). This is because it is mentioned that Rich has $5 more than 3 times the amount of money Aylen has. The sum of the savings is $101. Therefore the sum of the savings of Aylen and Rich is given by:
x + 3x + 5 = 101. Thus, Option C is the correct answer.
Solve the equation for x gives x = $24. This is Aylen's share. To calculate Rich's share, simply put x=24 in 3x+5. Thus, Rich's share will be $77.
In short, Rich's share = $77, Alan's share = $24, and this has been calculated using the equation x+3x+5=101 (Option C)!!!
To find the value of y, you need to plug a value into the x variable, in this case -8.
4x + 9y = -14 Substitute -8 for x
4 (-8) + 9y = -14 Multiply
-32 + 9y = -14 Start isolating the variable by adding 32 to both sides
9y = 18 Divide both sides by 9
y = 2
When x = -8, y = 2
