Explanation Given: Equation − x + 5 = 7 Approach: Solve the equations using addition and subtraction of integers. Addition of integers: Integers of same sign are added along with the same sign. Integers with different sign are subtracted and the sign of number having larger absolute value is given. Calculation: Given equation can be solved as: − x To determine (b) To solve: The equation 1 − x = − 13 To determine (b) To solve: The equation − x − 8 = − 9

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
