7

Step-by-step explanation:

Step 1: Subtract 3 from both sides.

6a+3−3=45−3

6a=42

Step 2: Divide both sides by 6.

6a /6 = 42 /6

8 / a = 8

Step-by-step explanation:

Simplifying

6a + -3 = 45

Reorder the terms:

-3 + 6a = 45

Solving

-3 + 6a = 45

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 6a = 45 + 3

Combine like terms: -3 + 3 = 0

0 + 6a = 45 + 3

6a = 45 + 3

Combine like terms: 45 + 3 = 48

6a = 48

Divide each side by '6'.

a = 8

Simplifying

a = 8
