Answer 1

Answer: See explanation

Step-by-step explanation:

7.) 2 (x - 1) = 45

2x - 2 = 45

Add 2 to both sides

2x = 47

x = 23.5

8.) 5x - 2 = 2 (4)

5x - 2 = 8

Add 2 to both sides

5x = 10

Divide both sides by 5

x = 2

9.) x = 2 (30)

x = 60

10.) 3x - 6 = 2 (x)

3x - 6 = 2x

Add 6 to both sides

3x = 2x + 6

Subtract 2x from both sides

3x - 2x = 6

x = 6

2x + 1

Substitute x for 6

2 (6) + 1

12 + 1 = 13

2y = 13

Divide both sides by 2

y = 6.5
