2x+x-7+8
3x-7=8
3x=15
x=5
for y
y=-2x+8
y=-2(5)+8
y=-10=8
y=-2
9/20 / 4/15

Step-by-step explanation:
Given
Tax amount=$1437.50
Tax percentaege=12.5%
So, we have to find the price of motorcycle whose 12.5% is 1437.50
Mathematically writing,
Let
x be the price of motorcycle without tax
then, the equation will be written as:
x*0.125=1437.50
x= 1437.50/0.125
x=11500
So the price of motorcycle without tax was $11500..
