#(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."#
