Question

5(x+1)+(x+2)=3 linear equation with verification​

Answer 1

Answer:

$5(x + 1) + (x + 2) = 3 \\ \\ 5x + 5 + x + 2 = 3 \\ \\ 6x + 7 = 3 \\ \\ 6x = 3 - 7 \\ \\ 6x = - 4 \\ \\ x = \frac{ - 4}{6} \\ \\ { \huge{ \boxed{ x = \frac{ - 2}{3} }}} \\ \\ { \huge{ \boxed{ \pink{verification \rightarrow}}}} \\ \\ \\ lhs \\ \\ 5(x + 1) + (x + 2) = 3 \\ \\ 5( \frac{ - 2}{3} + 1) + ( \frac{ - 2}{3} + 2) \\ \\ = 5( \frac{ - 2 + 3}{3} ) + ( \frac{ - 2 + 6}{3} ) \\ \\ = \frac{5}{3} + \frac{4}{3} \\ \\ = \frac{5 + 4}{3} \\ \\ = \frac{9}{3} \\ \\ = 3 \\ \\ = rhs \\ \\ hence \: verified$
