78 - 2x = 89 - 3x

Add 3x to both sides

78 + x = 89

Subtract 78 from both sides

x = 89 - 78

x = 11

I need help please and thank you.

kogti [31]

Step-by-step explanation:

$\frac{2x}{5} + \frac{1}{3} = \frac{7x - 2}{15}$

$\frac{6x + 5}{15} = \frac{7x - 2}{15}$

$6x + 5 = 7x - 2$

$6x - 7x = - 2 - 5$

$- x = - 7$

$x = 7$
