20% of $23.99 is 4.798
Therefore, discount is $4.80 (rounded off)
And the selling price of the sweater is $19.19
y=3x - 5....(i)
6x+3y=15.....(ii)
Then,
Keeping value of y in (ii)equation;
or,6x+3(3x-5)=15
or,6x+9x-15=15
or,15x=15+15
or,x=30/15
:x=2
Now, <em>Keeping</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>in</em><em> </em><em>(</em><em>i</em><em>)</em><em> </em><em>equation</em><em>;</em>
<em> </em>y= 3x-5
or, y= 3×2 - 5
or,y= 6-5
: y=1
