Question

6) Solve: () 4 (m + 3) = 18
(ii) -2(X+3) = 8​

Answer 1

Required Answer :

Explanation :

1.)

4(m+3) = 18

=> 4m + 12 = 18

=> 4m = 18 - 12

=> 4m = 6

=> m = 6/4

=> m = 3/2

so, the value of m = 3/2

Verification :

To verify this statement, we have to put the value of m in 4( m+3 ) = 18. And after it, we have to make LHS = RHS.

let's do it =>

$= > 4(m + 3) = 18 \: - - - - (m \: = \frac{3}{2} ) \\ = > 4( \frac{3}{2} + 3) = 18 \\ \\ = > 4( \frac{3 + 6}{2} ) = 18 \\ \\ = > 4 \times \frac{9}{2} = 18 \\ \\ = > \frac{36}{2} = 18 \\ = > 18 = 18$

Hence, by this verification, We find that LHS = RHS

so,

it is verified.

2.)

-2( x + 3) = 8

=> -2x - 6 = 8

=> -2x = 8+6

=> -2x = 14

=> -x = 14/2

=> -x = 7

so, the value of x = -7

Verification :-

To verify this answer, we have to put the value of x in -2(x+3)=8 and make LHS = RHS.

let's do it ===>

-2(-7+3) = 8

=> 14 -6 = 8

=> 8 = 8

LHS = RHS

hence verified

Answer 2

Answer: i) 4 (m+3) = 18

=) 4m+12 = 18

=) 4m = 18 - 12

=) 4m = 6

=) m = 6/4

=) m = 3 / 2

this is ur required answer u can verify this answer by putting the value of m in the question ...

ii) -2 ( x+3) = 8

=) -2 x - 6 = 8

=) -2x = 8 + 6

=) -2x= 14

=) -x= 14 / 2

= ) -x = 7

=) x = -7

this is ur required answer u can verify this by putting the value of x in the question ..

Step-by-step explanation:

itz akansha .. thanks for ur question xd ...
