For the following system of equations, what is the x-value of the solution?
Anastaziya [24]
Add x to both sides of the first equation. This makes 2y=6+x. Then Multiply it all by 3. This makes 6y=18+3x. Then multiply both sides by -1. This makes -6y=-18-3x. Then combine the two equations. 6y+ (-6y)=0, x+(-3x)=-2x, and 18+(-18)= 0. This leaves 0y=-2x+0, in other words, -2x=0 Then you can divide out the -2x from both sides. 0 divided by anything is 0. This leaves x=0

A motorist traveled 250 miles on 11 gallons of gas. With the same vehicle, about how far could he go on 16 gallons of gas? Round
krek1111 [17]

Answer: 363.6 miles.


Step-by-step explanation:

1. You know that the motorist traveled 250 miles on 11 gallons of gas. Then, to calculate how far could the motorist go on 16 gallons of gas (with the same vehicle), you only need to multiply  16 gallons by 250 miles and divide this by 11 gallons.

2. Keeping this on mind, let's call the distance the motorist could go on 16 gallons of gas x, then:

x=\frac{16gallons*250miles}{11gallons}

3. Therefore, you obtain the following result:

x=363.3miles

24= .25*x

Divide both sides by 0.25

24 - .25x

.25 - .25

x=96
