solve this system of equations using substitution y=2x - 4 x + 2y = 10 step 1: substitute for y in the second equation. which is the resulting equation?

Respuesta :

Answer:

5x - 8 = 10

Step-by-step explanation:

y = 2x - 4

x + 2y = 10

Substituting for y in equation 1 into equation 2 we get:_

x + 2(2x - 4)= 10

5x - 8 = 10

Answer

Step 1- x+2(2x-4)=10

Step 2- distribute 2

Step 3- x and 4x

Step 4- add 8

Step 5- divide 5

Step 6- first

Step 7- 3.2
