How many solutions does the system have?

3x + y = 8

2 + 2y = 8

x=2, y=2

Step-by-step explanation:

This question is a simultaneous equation

So let's solve

3x+y=8 ... (1)

2x+2y=8 ... (2)

Multiply (1) by 2

6x+2y=16 ... (3)

Substrate (2) From (3)

4x=8

Let's make x the subject of formula by dividing both sides by 4

x=2

So let's substitute the value of x into (1)

3x+y=8

3 (2) + y=8

6+y=8

y=8-6

y=2

Therefore x is 2, y is 2
