The value of x to the system of equations

They are both equal to y so you can set them equal to each other to solve for x:

14x - 6 = -4x + 48

18x = 54

x = 3

To solve for y just plug 3 into the x of one of the given equations

y = 14(3) - 6

y = 42 - 6

y = 36

To check:

36 = 14(3) - 6

36 = 42 - 6

36 = 36

36 = -4(3) + 48

36 = -12 + 48

36 = 36

Hope this helped!

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
