\text{Solve for }a of 3+0.5(4a+8)=9-2a

Solve 3+0.5(4a+8)=9-2a

Evaluate

3 + 0.5 (4 a + 8) = 9 - 2 a

Move the expression to the left side

3 + 0.5 (4 a + 8) - (9 - 2 a) = 0

Calculate the sum or difference

More Steps

- 6 + 0.5 (4 a + 8) + 2 a = 0

Calculate

More Steps

- 2 + 4 a = 0

Move the constant to the right-hand side and change its sign

4 a = 0 + 2

Removing 0 doesn't change the value,so remove it from the expression

4 a = 2

Divide both sides

\frac{4 a}{4} = \frac{2}{4}

Divide the numbers

a = \frac{2}{4}

Solution

a = \frac{1}{2}

Alternative Form

a = 0.5
