Question

8X+3=5X solve and prove LHS

Answer 1

Answer:

8x +3 = 5x

=> 8x -5x = -3

=> 3x = -3

=> x = -3/3 = -1.

so,

x = -1

putting x = -1 in LHS

8x +3

= 8*( -1) +3

= -8 + 3

= -5.

now,

rhs

5x = 5 ×(-1)

= -5

so,

LHS = rhs.

proved.

Answer 2

Answer:

$\implies8x + 3 = 5x \\ \\ \\ \implies8x - 5x =-3 \\ \\ \\ \implies3x =-3 \\ \\ \\ \implies \: x = -1 \\ \\ \\taking \: l.h.s. \\ \\ \\ \implies8x + 3 = 8 \times -1 + 3 \\ \\ \\ \implies-8+3=-5\\\\\\taking\:r.h.s.\\\\\\\implies5x=5×-1\\\\\\\implies-5\\\\\\hence\:verified$
