Joey has to solve the system of equations using substitution. he has completed the work shown. what should be his next step?

The next step is calculate the value of x

Step-by-step explanation:

The next step is substitute the value of y in the equation

x=10-5y

To find the value of x

so

x=10-5(2)=0

The value of x=0

To find the value of x

x = 0

Step-by-step explanation:

Equation1

3x + 6y = 12

Equation2

x + 5y = 10

Till now Joey have wrote equation 2 in terms of x and substituted the value of x in Equation 1

In result of it we calculated value of y = 2

Now put this value of y in any equation from above

let say Equation 1

3x + 6(2) = 12

3x = 12- 12

3x = 0

x = 0/3

x = 0

answer: what in the world is this
