Answer:
(4,2)
Step-by-step explanation:
System of Equations
Solve the following system of equations:
11x + 22y = 88
x = 10 - 3y [2]
By the substitution method.
We can divide the first equation by 11:
x + 2y = 8 [1]
Substitute x from [2] into [1]:
10 - 3y + 2y = 8
Simplifying:
10 - y = 8
Subtracting 10:
-y = -2
Multiplying by -1:
y = 2
From [2]:
x = 10 - 3y
x = 10 - 3*2 = 4
Solution: (4,2)
