Nettet1. mai 2024 · In the following exercises, determine whether the given number is a solution to the equation. x + 16 = 31, x = 15 w − 8 = 5, w = 3 −9n = 45, n = 54 4a = 72, a = 18 In the following exercises, solve the equation using the Subtraction Property of Equality. x + 7 = 19 y + 2 = −6 a + 1 3 = 5 3 n + 3.6 = 5.1 NettetA linear equation is an equation for a straight line. These are all linear equations: y = 2x + 1 : 5x = 6 + 3y : y/2 = 3 − x: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line . When x increases, y increases twice as fast, so we need 2x; Nettet6. okt. 2024 · I. Single Fractions on Each Side of the Equation Equations a), b) and c) in Example 24.1 fall into this category.
