Question

19. 6(1 - 4x) + 7(2 + 5x) = 53​

Answer 1

$\huge\underline\mathcal\blue{Solution}$

$\implies\sf 6(1-4x)+7(2+5x)=53$

$\implies\sf 6-24x+14+35x=53$

$\implies\sf 20+11x=53$

$\implies\sf 11x=53-20$

$\implies\sf x=\cancel\frac{33}{11}$

$\implies\sf x=3$

Answer 2

Answer:

19.6(1-4x)+7(2+5x)=53

114(1-4x)+14+35x

114-456x+14+35x

114+14-456x+35x=53

128-421x=53

v

x=75/421
