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#
#color(blue)"As a check"# 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."#
