Question

19. 3(x + 6) + 2(x + 3) = 64 check it​

Answer 1

Answer:

x=8

Step-by-step explanation:

3x+18+2x+6=64

5x+24=64

5x=64-24

5x=40

x=40/5

x=8

checking

3(8+6)+2(8+3)=64

3(14)+2(11)=64

42+22=64

64=64

LHS=RHS

Given :

$3(x + 6) + 2(x + 3) = 64$

To find :

The value of x

Solution :

→ $3(x + 6) + 2(x + 3) = 64$

→ $3x + 18 + 2x + 6 = 64$

→ $5x + 24 = 64$

→ $5x = 64 - 24$

→ $5x = 40$

→ $x = \frac {40}{5}$

→ $x = 8$

Check :

To check, we have to put the value of x in the expression, i.e., 8

→ $3(x + 6) + 2(x + 3) = 64$

→ $3(8 + 6) + 2(8 + 3) = 64$

→ $24 + 18 + 16 + 6 = 64$

→ $64 = 64$

$\implies \textbf {LHS = RHS}$

$\therefore \textbf {Hence, CHECKED!}$
