Solving by substitution y=-7x+6 with 5x+y=2

x=1/3,y=3

Step-by-step explanation:

y=7x+6equation1

5x+y=2equation2

substitute y into equation 2

5x+7x+6=2

12x+6=2

12x=2-6

12x=-4

x= -1/3

substitute X into equation 1

y=7x+6

y=7(-1/3)+6

y=-7/3+6

y=9/3

y=3

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
