What is the first step to solve the equation $$f - 225 = a$$ for f?

To solve for f, you would add 225 to both sides of the equation, resulting in $$f = a + 225$$ .

If $$398 = a + 28$$ , how do you solve for a?

To solve for a, subtract 28 from both sides: $$a = 398 - 28$$ .

What does the equation $$252 = \frac{c}{40}$$ imply about c?

It implies that c can be found by multiplying both sides by 40: $$c = 252 \times 40$$ .

How can you express the relationship 'the sum of a and 28 equals 398'?

This can be expressed as $$a + 28 = 398$$ .

What is the solution for j in the equation $$\frac{j}{37} = 293$$ ?

To solve for j, multiply both sides by 37: $$j = 293 \times 37$$ .

How do you isolate h in the equation $$343h = 159$$ ?

To isolate h, divide both sides by 343: $$h = \frac{159}{343}$$ .

What is the meaning of the term 'variable' in mathematics?

A variable is a symbol used to represent an unknown value in an equation or expression.

What is the difference between an equation and an expression?

An equation states that two expressions are equal, while an expression is a combination of numbers, variables, and operations without an equality sign.

How do you check if your solution to an equation is correct?

You can check your solution by substituting the value back into the original equation to see if both sides are equal.
