Question

solve for the point where these two equations cross using substitution.
4x + 6y = 14, x - 4y = -14

Answer 1

Answer:

the points are (-1.28,3.18)

Step-by-step explanation:

x - 4y = -14

x = -14 + 4y......1

sub this into the first equation

4(-14 + 4y) +6y = 14

-56 + 16y + 6y = 14

22y = 70

y = 3.18.........2

Sub 2 into 1

x = -14 + 12.72

x = -1.28
