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!

Please help me with this
kirill [66]

Answer:

15/2 or 7.5

Step-by-step explanation:

5/6 (x + 1/2 + 4)

distribute 5/6 to each number

5/6x + 5/12 + 10/3

change the fraction 10/3 so that it will have the same denominator as 5/12

\frac{10}{3} *4 = 40/12

5/6x + 5/12 + 40/12\\5/6x + 45/12

divide both sides by 5/6

x = 9/2

5/6*9/2+5/12+10/3 = \frac{15}{2}
