Question

solve by first clearing decimals.

\\-3.2 = -4 + 0.8b\\

Explanation:

Multiply both sides by 10 to clear decimals

$$ 10 \cdot (-3.2) = 10 \cdot (-4 + 0.8b) $$

$$ -32 = -40 + 8b $$

Isolate the variable term

$$ -32 + 40 = 8b $$

$$ 8 = 8b $$

Solve for b

$$ b = \frac{8}{8} $$

$$ b = 1 $$

Answer:

\(b = 1\)
