3y + 1 = 7y + 9​

Answer 1

hope this helps................

Answer 2

Answer:

$3y + 1 = 7y + 9 \\ 3y - 7y = 9 - 1 \\ - 5y = 8 \\ y = \frac{ - 8}{4} \: \: \: \: \: \: \: \: answer \\ now$

$putting \: the \: value \: of \: y \: = \frac{ - 8}{4}$

$lhs = \: 3 \times \frac{ - 8}{4 } + 1$

$\frac{ - 24}{4} + 1 \\ \frac{ - 24 +4}{4} \\ \frac{ - 20}{4} \\ = - 5$

R. h. s=7*-8/4+9

-56/4+9

$\frac{ - 56 + 36}{4} \\ \frac{ - 20}{4 } \\ - 5$

L. H. S = R. H. S
