Question

4. Solve the following equations by the transposing
method and check your answer.
(a) 5x - 2x + 7 = x + 1​

Answer 1

Answer:

- 3

Step-by-step explanation:

5x - 2x + 7 = x +1

3x + 7 = x + 1

transport x toilet hand side and 7 to right hand side

3x - x = 1- 7

2x = - 6

transport 2 to right hand side

x = - 6 ÷ 2

x = - 3

Answer 2

$5x - 2x + 7 = x + 1 \\ = 3x + 7 = x + 1 \\ = 3x - x = 1 - 7 \\ = 2x = \: - 6 \\ = x = \frac{ - 6}{2 } \\ = - 3 \: (ans)$
