Question

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

Answer 1

Answer:

x = 3/2

Step-by-step explanation:

The equation reads:

$\frac{4}{3} x-\frac{2}{5} =\frac{7}{5} x-\frac{1}{2}$

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:

$-\frac{2}{5} +\frac{1}{2} =\frac{7}{5} x-\frac{4}{3} x\\\frac{-4+5}{10} =\frac{21-20}{15} x\\\frac{1}{10}=\frac{1}{15} x\\x=\frac{15}{10} \\x=\frac{3}{2}$
