Question

7 X / 2 - (- 5 X / 2) =20X / 3 + 10​

Answer 1

$\frac{7x}{2} - ( \frac{-5x}{2} ) = \frac{20x}{3} + 10$

$\frac{7x}{2} + \frac{5x}{2} = \frac{20x}{3} +10$

$\frac{6x}{1} = \frac{20x+30}{3}$

${\bold{\blue{cross-multiply}}}$

$3×(6x) = 20x+30$

$18x = 20x+30$

$18x - 20x = 30$

$x = \frac{60}{-2}$

$x = -15$
