1 Solve:

8r + 4 = 10 + 2r

2 Solve:

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

3 5 + 3 (q - 4) = 2 (q + 1)

4 7x - 4 = - 2x + 1 + 9x - 5

5 Solve:

8x + 6 - 9x = 2 - x - 15

Step-by-step explanation:

1 Solve:

8r + 4 = 10 + 2r

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

8r - 2r = 10-4

6r = 6

r = 6/6 = 1

2 Solve:

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

-2x - 6 = 4x - 3

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

-2x - 4x = - 3 + 6

-6x = 3

x = 3/-6

x = - 1/2

3 Solve

5 + 3 (q - 4) = 2 (q + 1)

5 + 3q - 12 = 2q+2

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

3q - 2q = 2 + 12 - 5

q = 9

4. Solve

7x - 4 = - 2x + 1 + 9x - 5

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

7x + 2x-9x = 1 - 5 + 4

0 = 0

5 Solve:

8x + 6 - 9x = 2 - x - 15

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

8x - 9x + x = 2 - 15 - 6

0x = - 19

0 = 19
