Help with substitution show work please

Solution of given system of equations is: x=4, y=-2 or (4,-2)

Step-by-step explanation:

Solve the equation using substitution

4x+y=14

x-2y=8

Substitution method involves placing value of x or y from one equation to other equation.

We have

Finding value of x from equation 2

x-2y=8

x=2y+8

Put this value of x in equation 1

We get y=-2

Now, put value of y into equation 2 to find value of x

We get x = 4

So, solution of given system of equations is: x=4, y=-2 or (4,-2)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
