Perform the indicated operation.
(25m 2 - 20m + 4) ÷ (5m - 2)
2m- 5
5m- 2
5m+ 2

(25m^2 - 20m + 4) ÷ (5m - 2) = [(5m - 2)(5m - 2)]/(5m - 2) = 5m - 2

7x - 3y = 4 multiple 4 on both sides the result is:

28x - 12y = 16 (equation 1)

2x - 4y = 1 multiple -3 on both sides the result is:

-6x + 12y = -3 (equation 2)

adding up equation 1 and 2 the result is:

22x = 13

x = 13/22

7(13/22) - 3y = 4

91/22 - 3y = 4

-3y = 4 - 91/22 = 88/22 - 91/22 = -3/22

y = (-3/22)/(-3) = 1/22

The solution for the system 7x - 3y = 4 2x - 4y = 1 is (13/22, 1/22)

28x - 12y = 16 (equation 1)

2x - 4y = 1 multiple -3 on both sides the result is:

-6x + 12y = -3 (equation 2)

adding up equation 1 and 2 the result is:

22x = 13

x = 13/22

7(13/22) - 3y = 4

91/22 - 3y = 4

-3y = 4 - 91/22 = 88/22 - 91/22 = -3/22

y = (-3/22)/(-3) = 1/22

The solution for the system 7x - 3y = 4 2x - 4y = 1 is (13/22, 1/22)
