Question

7×-21-4×+13+2×=41-5×-7+6×​

Answer 1

Answer:

thus

9x-10=34+x

7x=44

x=6.29

Answer 2

Answer : X = 10.5

Step-by-step explanation:

$= 7x - 21 - 4x + 13 + 2x \\ = 41 - 5 x - 7 + 6x$

$= 7x -4x + 2x - 21 + 13 \\ = 41 - 7 + 6x - 5x$

$= 3x + 2x - 21 + 13 \\ = 34 + x$

$= 5x - 8 = 34 + x$

Now we have to traspose x to l.h.s and -8 to r.h.s

$= 5x - x = 34 + 8$

$4x = 42$

Now transpose 4 to r.h.s

$= x = 42 \div 4$

$= x = 10.5$

Answer : x= 10.5
