Question

If 5x/2 - 4 = 6x - 3/2, then the value of 7x+5 is equal to ​

Answer 1

Answer:

$\frac{5x}{2} - 4 = 6x - \frac{3}{2} \\ \frac{5x}{2} - 6x = - \frac{3}{2} + 4 \\ \frac{5x}{2} - 6x = - \frac{3}{2} + \frac{8}{2} \\ \frac{5x}{2} - 6x = \frac{5}{2} \\ 5x - 6x = \frac{5}{2} \times 2 \\ 5x - 6x = 5 \\ - x = 5 \\ x = - 5$
