The substitution method is used to solve the equation x+y=10. The given equation has infinitely many solutions.
The given equation is x+y=10. We will use the substitution method to solve it.
Step 1: Solve one equation for one variable in terms of the other.
Let's solve the given equation for x:
x = 10 - y
Step 2: Substitute the value of x in the other equation.
Substituting the value of x in the equation x + y = 10:
(10 - y) + y = 10
10 - y + y = 10
10 = 10
Step 3: Simplify the equation.
The equation 10 = 10 is true. So, the given equation x + y = 10 has infinitely many solutions.
