Explicație pas cu pas:
[tex]\bf \dfrac{2x + 10 - 3x}{10} = \dfrac{x + 3 - x - 1}{4} \implies[/tex]
[tex]\bf \dfrac{10 - x}{10} = \dfrac{2^{(2}~}{4} \implies \dfrac{10 - x}{10} = \dfrac{1}{2} \implies10\cdot1 = 2\cdot(10 - x) \implies[/tex]
[tex]\bf 10 = 20-2x \implies 2x = 10 ~~\bigg|:2~~ \implies \red{ \boxed{\bf x = 5}}[/tex]
