Answer:
X=2, y=8
Step-by-step explanation:
Y=-x+10 equation 1
y=2x+4 equation 2
-x+10=2x+4. Substitute y of first equation into 2nd equation
-x-2x+10=4
-3x=4-10
-3x=-6
x=2
solve for y by inserting x value into either equation
y=-x+10
y=-2+10
y=8
check answer
y=2x+4
8=2(2)+4
8=4+4
8=8
If you would like to know what is the selling price of the sweater, you can calculate this using the following steps:
40% of x is $8
40% * x = 8
40/100 * x = 8 /*100/40
x = 8 * 100 / 40
x = $20
Result: The selling price of the sweater is $20.
