Linear equations problem solving
NettetSolved Problems on Linear Equations Example 1: Solve 3x – 5 = 10 and check the answer. Solution: 3x – 5 = 10 Transposing -5 to RHS, 3x = 10 + 5 3x = 15 Divide each side by 3, we get 3x/3 = 15/3 x = 5 Checking: Substituting x = 5 in the given equation. 3 (5) – 5 = 10 15 – 5 = 10 10 = 10 Result is true. Example 2: Solve (3x + 4)/ (x – 6) = 2/3 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
