Question

Solve the following:

A) 2(x+3)=x-4

b) 4(5x-2)=2(9x+3)

Answer 1

`A) \: x = - 10 \\ B) \: x = 7`

Explanation:

`A) \\ = > 2(x + 3) = x - 4 \\ \\ = > (2 * x) + (2 * 3) = x - 4 \\ \\ = > 2x + 6 = x - 4 \\ \\ = > 2x - x + 6 = - 4 \\ \\ = > x + 6 = - 4 \\ \\ = > x = - 4 - 6 \\ \\ = > x = - 10 \\ \\ \\ B) \\ = >4(5x-2)=2(9x+3) \\ \\ = > (4 * 5x) - (4 * 2) = (2 * 9x) + (2 * 3) \\ \\ = > 20x - 8 = 18x + 6 \\ \\ = > 20x - 18x - 8 = 6 \\ \\ = > 2x - 8 = 6 \\ \\ = > 2x = 6 + 8 \\ \\ = > 2x = 14 \\ \\ = > x = (14)/(2) \\ \\ = > x = 7`
