Question

Me ajuda por favor ​

Answer 1

Resposta:

e) $x=\frac{-17}{2}$

f) $x = 16$

Explicação passo-a-passo:

e)

$\frac{x+3}{4}-\frac{x-1}{3}=\frac{7}{2}\\x+3-\frac{4x-4}{3}=\frac{28}{8}\\3x + 9 - 4x - 4 = \frac{84}{24}\\-x=\frac{84}{24}-5\\x=\frac{-17}{2}$

f)

$\frac{4x-1}{10}-2=\frac{4}{5}-\frac{2-x}{4}\\4x-1-20=\frac{40}{5}-\frac{20-10x}{4}\\4x+\frac{20- 10x}{4}=\frac{40}{5}+21\\16x+20-10x=\frac{160}{5}+84\\6x=\frac{160}{5}+84-20\\6x=96\\x=16$
