Question

Identify the system using any method. 2x + 2y = 3 x = 4y - 1

Answer 1

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)
