Question

5(4x+5)=5(x+2 1/2)-1/2(7x+12)​

Answer 1

Answer:

$x = - \frac{ 13}{37}$

Step-by-step explanation:

$5(4x + 5) = 5(x + 2 \frac{1}{2} ) - \frac{1}{2} (7x + 12) \\ 20x + 25 = 5x + \frac{25}{2} - \frac{7x}{2} + \frac{12}{2} \\ 20x - 5x + 25 - 6 = \frac{25}{2} - \frac{7x}{2} \\ 15x + 19 = \frac{25 - 7x}{2} \\ 30x + 38 = 25 - 7x \\ 30x + 7x = 25 - 38 \\ 37x = - 13 \\ x = - \frac{ 13}{37}$
