Question

Me ayudan a resolver 4/3×-2/5=7/5×-1/2

Answer 1

x = 3/2

Explanation:

The equation reads:

`(4)/(3) x-(2)/(5) =(7)/(5) x-(1)/(2)`

So we start by grouping all terms in x on the right, and all pure numerical terms on the left, and then combine like-terms and solve for x:

`-(2)/(5) +(1)/(2) =(7)/(5) x-(4)/(3) x\\(-4+5)/(10) =(21-20)/(15) x\\(1)/(10)=(1)/(15) x\\x=(15)/(10) \\x=(3)/(2)`
