The x coordinate of the solution to the system of equations y=x+4 and 3y=-2x+2
Vera_Pavlovna [14]
<h2>Hello!</h2>

The answer is:

The x-coordinate of the solution to the system of equations is:

x=-2

<h2>Why?</h2>

We can solve the problem writing both equations as a system of equations.

So, we are given the equations:

\left \{ {{y=x+4} \atop {3y=-2x+2}} \right.

Then, solving by reduction we have:

Multiplying the first equation by 2 in order to reduce the variable "x", we have:

\left \{ {{2y=2x+2*4} \atop {3y=-2x+2}} \right.

5y=2x-2x+8+2\\\\5y=8+2\\\\y=\frac{10}{5}=2

Now, substituting "y" into the first equation, to isolate "x" we have:

y=x+4\\\\2=x+4\\\\x=2-4=-2

Hence we have that the x-coordinate of the solution to the system of equations is

x=-2

Have a nice day!

Answer:

  • y = 0.35x

Step-by-step explanation:

<u>Janet ⇒ 3 postcards ⇒ $1.05 </u>

  • Cost of postcard: 1.05/3 = $0.35

<u>Rosi ⇒ 5 postcards ⇒ $1.75 </u>

  • Cost of postcard: 1.75/5 = $0.35

<u>Tanya ⇒ 8 postcards ⇒ $2.80</u>

  • Cost of postcard: $2.80/8 = $0.35

<u>We see in all 3 cases cost of postcard is same, the cost and numbers are proportional and the relationship is:</u>

  • y = 0.35x
