Question

Y=2X-2
Y=4X-4 We. Solve these equations by graphically let us denote the number of pantsby x and the number of skirt by y then the equations formed are:

Answer 1

Answer:

We can solve this problem through graphically also

Hence, the number of pants she purchased is 1 and the number of skirts, she purchased is zero i.e. she didn't buy any skirt.

Step-by-step explanation:

Let the number of pants = x

Let the number of skirts = y

According to the equation

Number of skirts = 2(Number of pants) - 2

y=2x−2 (i)

Also, Number of skirts = 4(Number of pants) - 4

y=4x−4 (ii)

Substituting the value of y=4x−4 in eq

n

 (ii), we get

y=4(1)−4=0

∴x=1,y=0 is the solution of the pair of linear equations.
