Step 1.1.1

Apply the distributive property.

$8 a + 8 \cdot - 3 - (a - 3) = 0.7$

Step 1.1.2

Multiply

$8$ by

$- 3$ .

$8 a - 24 - (a - 3) = 0.7$

Step 1.1.3

Apply the distributive property.

$8 a - 24 - a - - 3 = 0.7$

Step 1.1.4

Multiply

$- 1$ by

$- 3$ .

$8 a - 24 - a + 3 = 0.7$

$8 a - 24 - a + 3 = 0.7$

Step 1.2.1

Subtract

$a$ from

$8 a$ .

$7 a - 24 + 3 = 0.7$

Step 1.2.2

Add

$- 24$ and

$3$ .

$7 a - 21 = 0.7$

$7 a - 21 = 0.7$

$7 a - 21 = 0.7$

Step 2
