1. 4x + 3(x-9) = 19 2. 2(x-4) + 5x = 3

3. 60 = 8y - 3(y-10)

4. 40 + 3c = 3 + 9(c-2)

1) 4x + 3(x-9) = 19

or, 4x + 3x - 27 = 19

or, 7x = 19+27

or, 7x = 46

or, x = 46/7

◆ x = 6.57

2) 2(x-4) + 5x = 3

or, 2x - 8 + 5x = 3

or, 7x = 3+8

or, x = 11/7

◆ x = 1.57

3) 60 = 8y - 3(y-10)

or, 60 = 8y - 3y + 30

or, 60 - 30 = 5y

or, y = 30/5

◆ y = 6

4) 40 + 3c = 3 + 9(c-2)

or, 40 + 3c = 3 + 9c - 18

or, 40 + 3c = 9c - 15

or, 9c - 3c = 40 + 15

or, 6c = 55

◆c = 9.166

I hope you understand..

Thank you...♥♥

Step-by-step explanation:

1. 46/7 or 6 4/7 or 6.57

2. 11/7 or 1 4/7 or 1.57

3. 6

4. 55/6 or 9 1/6 or 9.16

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
