(2,5)

Explanation:

Substitute x = 2 into the equation and solve for y

rArr(6xx2)-y=7

rArr12-y=7

subtract 12 from both sides.

cancel(12)cancel(-12)-y=7-12

rArr-y=-5rArry=5

Substitute these values into the left side and if equal to the right side then they are the solution.

rArr(6xx2)-5=12-5=7=" right side"

rArr(2,5)" is a solution to the equation."
