Step 2.1.1

Apply the distributive property.

2 p + 2 \cdot 2.9 - 2.35 = 7.25

$2 p + 2 \cdot 2.9 - 2.35 = 7.25$

Step 2.1.2

Multiply

2

$2$ by

2.9

$2.9$ .

2 p + 5.8 - 2.35 = 7.25

$2 p + 5.8 - 2.35 = 7.25$

2 p + 5.8 - 2.35 = 7.25

$2 p + 5.8 - 2.35 = 7.25$

Step 2.2

Subtract

2.35

$2.35$ from

5.8

$5.8$ .

2 p + 3.45 = 7.25

$2 p + 3.45 = 7.25$

2 p + 3.45 = 7.25

$2 p + 3.45 = 7.25$

Step 3.1

Subtract

3.45

$3.45$ from both sides of the equation.

2 p = 7.25 - 3.45

$2 p = 7.25 - 3.45$

Step 3.2

Subtract

3.45

$3.45$ from

7.25

$7.25$ .

2 p = 3.8

$2 p = 3.8$

2 p = 3.8

$2 p = 3.8$
