y=3x−5 y=x−1 is ( 2 , 1 )a solution of the system?

Answer : (2,1) is a solution of the system.

Step-by-step explanation :

As we are given that:

y = 3x-5    (1)

y = x-1      (2)

Now equating equation 1 and 2, we get the value of 'x'.

3x-5 = x-1

3x-x = -1+5

2x = 4

x = 4/2

x = 2

Now put the value of 'x' in equation 2, we get the value of 'y'.

y = x-1

y = 2-1

y = 1

Thus, the value of x = 2 and y = 1 that means (2,1) is a solution of the system.

Hence, the (2,1) is a solution of the system.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
