Identify the system using any method.
2x + 2y = 3
x = 4y - 1
1 answer:
Answer is the 2nd choice ( 1, 1/2)
Step by step
Solve for y
Substitute x= value into equation
2(4y -1) + 2y = 3
Distribute multiply
8y - 2 + 2y = 3
Combine
10y -2 = 3
Add 2 to both sides to isolate y
10y -2 + 2 = 3 + 2
Combine
10y = 5
Divide both sides by 10 to solve for y
10/10 y = 5/10
y = 5/10 simplified to 1/2
Now substitute your y value into the equation
x = (4)(1/2) -1
x = 2 - 1
x = 1
Answer is ( 1, 1/2)
