$\frac{x}{2.5}$ = $\frac{7}{5}$

x×5=5x

2.5×7=17.5

5x=17.5

x=17.5/5

x=3.5

Could someone help me step by step with this question?

a_sh-v [17]

$\frac{2}{3}(9+x)=-5(4-x) \\ \\ 3*\frac{2}{3}(9+x)=3*[-5(4-x)] \\ \\ 2(9+x)=-15(4-x) \\ \\ 18+2x=-60+15x \\ \\ -13x=-78 \\ \\ \cfrac{-13x}{-13} = \cfrac{-78}{-13} \\ \\ x=6$
