Question

Solve each equation

$\mathit{a}\mathbf{=}\mathbf{32}\mathbf{-}\mathbf{9}\mathbf{\left(}\mathbf{2}\mathbf{\right)}$

Short answer

The value of a is 14.

Step-by-step solution

Step 1. Definition.

Equation: An equation is a mathematical statement that two expressions are equal. An equation will always contain an equal sign with an expression on each side.

Step 2. Order of Operations.

BODMAS

B – Brackets First

O – Orders (i.e. Powers and Square Roots etc.)

D – Division

M – Multiplication

A – Addition

S – Subtraction

Step 3. Apply BODMAS Rule.

$a=32-9\left(2\right)$Original equation

First, we multiply 9 by 2 (BODMAS Rule)

$\Rightarrow a=32-18$

Subtract the numbers

$\Rightarrow a=14$

Thus, the value of a is 14
