Mark' s age plus three times nik's age is equal to 54. twice mark's age plus four times nik's age is equal to 80. how old is nik?

Nik's age: x

Here is a system of equations that we can set up based on the information...
x+3y=54
2y+4x=80

Rearrange these...
x+3y=54
4x+2y=80

x+3y=54 solve an equation for y
4x+2y=80
2y=80-4x
y=40-2x

Plug in 40-2x for y in the other equation...
x+3(40-2x)=54
x+120-2x=54
-x+120=54
-x=-66
x=66

Nik is 66 years old.

Hope this helps! Best wishes:)

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
