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.

What is the solution to y-7>3+2y
Alex17521 [72]

Solving:

-7 + y = 3 + 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

-7 + y + -2y = 3 + 2y + -2y

Combine like terms: y + -2y = -1y

-7 + -1y = 3 + 2y + -2y

Combine like terms: 2y + -2y = 0

-7 + -1y = 3 + 0

-7 + -1y = 3

Add '7' to each side of the equation.

-7 + 7 + -1y = 3 + 7

Combine like terms: -7 + 7 = 0

0 + -1y = 3 + 7

-1y = 3 + 7

Combine like terms: 3 + 7 = 10

-1y = 10

Divide each side by '-1'.

y = -10

Hope it helps. (:
