Question

answer it plz I'll mark as brainliest

Answer 1

21y+12 = -4y-8
25y = -20
y = -20/25
y = -4/5

Answer 2

Heya dear user !!!

Here is your answer,

================================

$\frac{7y + 4}{y + 2} = \frac{ - 4}{3} \\ \\ cross \: \: multiplication \\ \\ 3(7y + 4) = - 4(y + 2) \\ \\ 21y + 12 = - 4y - 8 \\ \\ 21y + 4y = - 8 - 12 \\ \\ 25y = - 20 \\ \\ y = \frac{ - 20}{25} \\ \\ y = \frac{ - 4}{5}$

Verifiacation

$L.H.S = \frac{7y + 4}{y + 2} \\ \\ \frac{(7 \times \frac{ - 4}{5} + 4) }{ (\frac{ - 4}{5} + 2)} \\ \\ \frac{ (\frac{ - 28}{5} + 4 )}{ (\frac{ - 4}{5} + 2)} \\ \\ \frac{ (\frac{ - 28 + 20}{5} )}{ (\frac{ - 4 + 10}{5} )} \\ \\ \frac{ - 8}{5} \div \frac{6}{5} \\ \\ \frac{ - 8}{5} \times \frac{5}{6} \\ \\ \frac{ - 4}{5} = R.H.S(verified)$

================================

Hope it helps.
