The above budget I submitted into fraction
2x-12=-40
Add 12 to both sides
2x=-20
Divide by 2 to both sides
x=-10
Answer:
25.2
Step-by-step explanation:
I'll assume you wrote:
So when x = 4:
≅ 
Let's make two expressions.
4.92+3.79x
This represents the car service's cost, which x being miles.
4.2x
This is the most Jason wants to spend. Let's make them equal.
4.92+3.79x=4.2x
We need to get x by itself, Let subtract 3.79x from both sides.
4.92=0.41x
Let's divide.
4.92÷0.41=12
So, he should not drive no more than 12 miles.
Answer:
x = 
y + 20
[Given]
4x - 6y = 20
[Add 6y to both sides of the equation]
4x = 6y + 20
[Divide both sides of the equation by 4]
x = 
y + 20
[Simplify , both 6 and 4 are divisible by 2]
x = y + 20
