1 Solve:

Answer 1

Answer:

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
