Solve this system of equations using substitution:
y = 2x-4
x + 2y = 10
Step 1: Substitute for hin the second equation. Which is
the resulting equation?
2x - 4 = 10
x + 2x - 4 = 10
x + 2(2x - 4) = 10

Respuesta :

Answer:

x + 2(2x-4) = 10

Step-by-step explanation:

Here in this question, we want to select which is the correct answer if we substitute for the value of y in the second equation, using the first.

In the first, we have;

y = 2x -4

Now, let’s input this value of y into the second equation.

By direct substitution, what we have is the following;

x + 2y = 10

—-> x + 2(2x -4) = 10
