Question

Substitution for Y+6X-11 and -2X-3Y=-7

Answer 1

y = 5/3 x = 19/9

Explanation:

Solve equation [2] for the variable y

[2] 3y = 5

[2] y = 5/3 Plug this in for variable y in equation [1]

[1] (5/3) - 6x = -11

[1] - 6x = -38/3

[1] - 18x = -38

Solve equation [1] for the variable x

[1] 18x = 38

[1] x = 19/9

By now we know this much :

y = 5/3

x = 19/9

We are done
