Hi there!!
First, Let plain shirts be x
Let fancy shirts be y
x + y = 7
15x + 28y = 131
Multiply first equation by 28 to eliminate y:
28x + 28y = 196
<span>15x + 28y = 131
</span>Subtracting the two equations:
13x = 65
<span>x = 5 </span>
Substituting x to get y:
x + y = 7
5 + y = 7
<span>y = 2 </span>
<span>Answer: 5 plain shirts and 2 fancy shirts
</span>
Hope this helps u!!
Have an amazing rest of ur day:)))

Answer:

Step-by-step explanation:
To find the slope of the given line, slope is the rise divided by the run of a line.
Slope =
Picking points (4, 18) and (8, 12)
Now;
x₁ = 4
y₁ = 18
x₂ = 8
y₂ = 12
Slope =
=
=
