Question

(xii) 3(x + 6) + 2(x + 3) = 64​

Answer 1

$\boxed{\boxed{\underline{\huge{\bold{\green{\mathfrak{Answer}}}}}}}$

$3(x + 6) + 2(x + 3) = 64 \\ 3x + 18 + 2x + 6 = 64 \\ 5x + 24 = 64 \\ 5x = 64 - 24 \\ 5x = 40 \\ x = \frac{40}{5}$

$\boxed{\boxed{\underline{\huge{\bold{\green{\mathfrak{x=8}}}}}}}$

Answer 2

Answer:

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

=>3x-18+2x+6=64

=>5x+24=64

=>5x=64-24

=>5x=40

=>x=8
