Question

please help 50 points!!!! answer 1-5 please if you can show how you got the answer if you cant its ok at least show how you got one please

Answer 1

• given below ↓

Step-by-step explanation:

1)

y = 3x + 6

y = 4x

insert equation 2 into equation 1

3x + 6 = 4x

4x - 3x = 6

x = 6

y = 4x

y = 4(6)

y = 24

solution: (6,24)

2)

y = 2x - 4

y = 3x

3x = 2x - 4

3x -2x = -4

x = -4

y = 3(-4)

y = -12

solution: (-4,-12)

3)

y = 4x+ 3

y = 5x

5x = 4x + 3

5x - 4x = 3

x = 3

y = 5x

y = 5(3)

y = 15

solutions: (3,15)

4)

y = 3x -5

y = 4x

insert equation 2 into 1

3x -5 = 4x

4x - 3x = -5

x = -5

y = 4x

y = 4(-5)

y = -20

solution: (-5,-20)

5)

y = x + 2

y = 2x

insert equation 2 into 1

2x = x + 2

x = 2

y = 2x

y = 2(2)

y = 4

solution: (2,4)
