Question

2x + 2y = 4 -x+ 2y = 4​

Answer 1

The answer is Y=2 I’m pretty sure

Answer 2

x = 0, y = 2

Explanation:

We can use substitution method to substitute 2y into 2x + 2y = 4.

-x + 2y = 4

2y = 4 + x --- Equation 1

2x + 2y = 4 --- Equation 2

Substitute Equation 1 into Equation 2:

2x + 2y = 4

2x + 4 + x = 4

3x + 4 = 4

Isolate 3x.

3x = 4-4

= 0

Find x.

x = 0 ÷ 3

x = 0

Substitute x = 0 into Equation 1:

2y = 4 + x

2y = 4 + 0

= 4

Find y.

y = 4 ÷ 2

y = 2
