## How do you write a math solution?

When you write your solution you should:Give each important definition or equation its own line.Don’t bury too much algebra in a paragraph. Label equations or formulas or lemmas or cases you will use later very clearly.Remember that there’s always more paper.

## How do you write a math conclusion?

The middle section is all of the mathematical working. The Conclusion summarises your report giving information about the problem that you had to solve, the mathematical processes used to solve the problem, and discussion on how you solved the problem. The Introduction. This must be placed at the start.

## What does a equation look like?

An equation is written as two expressions, connected by an equals sign (“=”). The expressions on the two sides of the equals sign are called the “left-hand side” and “right-hand side” of the equation. , consisting of just one term. The unknowns are x and y, and the parameters are A, B, and C.

## What is simple simultaneous equations?

Simultaneous equations are two equations, each with the same two unknowns and are “simultaneous” because they are solved together.

## What is the formula for simultaneous equation?

This is a process which involves removing or eliminating one of the unknowns to leave a single equation which involves the other unknown. The method is best illustrated by example. Example Solve the simultaneous equations 3x + 2y = 36 (1) 5x + 4y = 64 (2) . y = 6 Hence the full solution is x = 8, y = 6.
