Question

solve the following question 7+2(a+1) - 3a=59​

Answer 1

Answer:

a=50

Step-by-step explanation:

7+2(a+1)-3a=59

7+2a+2-3a=59

9-a=59

-a=-50

a=50

Answer 2

$\large\underline\purple{\bold{Solution :- }}$

$\blue{ \bf \: 7 + 2(a + 1) - 3a = 59}$

$\rm :\implies\:7 + 2a + 2 - 3a = 59$

$\rm :\implies\:9 - a = 59$

$\rm :\implies \large\boxed{ \pink{\:a \: = \: - \: 50}}$

Verification

Consider LHS

$\rm :\implies\: 7 + 2(a + 1) - 3a$

Now, on substituting a = - 50, we get

$\rm :\implies\:7 + 2( - 50 + 1) - 3 \times ( - 50)$

$\rm :\implies\:7 + 2 \times ( - 49) + 150$

$\rm :\implies\:157 - 98$

$\rm :\implies\:59$

$\bf \: = \: RHS$

$\rm :\implies\: \boxed{ \pink{ \bf \: Hence, \: verified \: \: }}$
