Question

2x + y = 7
-2x - y = 6
Solve systems of equations by substitution

Answer 1

No solution.

Explanation:

2x + y = 7

-2x - y = 6

From the first equation:

y = 7 - 2x

Plug this into the second equation:

-2x - (7 - 2x) = 6

-2x + 2x = 6 + 7

0 = 13

this doesn't make sense so theer is:

No solution.
