Question

slove:15(x-1)+4(x+3)=2(7+x)​

Answer 1

Answer:

15x-1x+4x+12 = 14 +2x

14x +4x +12 =14+2x

18x+ 12= 14 +2 x

18x-2x =14-12

16x= 2

x=2/16

x = 1/8

Explanation:

$15(x-1)+4(x+3)=2(7+x)$

$= > 15x - 15 + 4x + 12 = 14 + 2x$

$= > 15x + 4x - 15 + 12 = 14 + 2x$

$= > 19x - 2x - 15 + 12 - 14$

$= > 17x - 15 - 2$

$= > 17x - 17 = 0$

$= > 17x = 17$

$= > x = \frac{17}{17} = 1$

$\bold\fcolorbox{aqua}{orange}{Answer}$$\bold{x = \frac{17}{17} = 1}$

Check :-

$15(x-1)+4(x+3)=2(7+x)$

$= > 15(1 - 1) + 4(1 + 3) = 2(7 + 1)$

$= > 0 + 4 \times 4 = 2 \times 8$

$= > 16 = 16$
