Hi there.
The answer is (-2,7). The second choice.
Explanation:
We can use the graph method or the solving method.
For the graph method, find where both graphs intercept and that is x = - 2 y = 7.
But if you don't use the graph method. We can solve the equation.
Convert the expressions in simplified form.
Then combine both equations.
Because there is the denominator. We get rid of it.
Multiply the whole equation by 2.
Since it is the two variables linear equations, we need to find y-value too.
Substitute x = -2 in any given equations.
I will substitute x = -2 in y = 5-x
Substitute x = -2 in the equation.
Thus, the answer is x = -2, y = 7
Or
(-2,7)
