Question

Qual o valor da equação X - 3/4 - X + 5/2 = x ?

Answer 1

$x-\frac{3}{4}-x+\frac{5}{2}=x \\ \\ x=\frac{5}{2}-\frac{3}{4} \\ \\ x=\frac{10-3}{4} \\ \\ \boxed{x=\frac{7}{4}}$

Answer 2

x - 3 - x + 5 = x
    4         2
mmc (2, 4) = 4
4x - 3 - 4x + 10 = 4x
4x - 4x - 4x = 3 - 10
- 4x = - 7
x = - 7 ÷ (- 4)
x = 1,75 ou 4/7
