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

Answer:
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
Answer:
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
