Question

Solve by cross-multiplication method.
x-3/x-3=5​

Answer 1

Answer:

3

Step-by-step explanation:

x - 3/ x - 3 = 5

1(x-3) = 5(x-3)

x-3 = 5x - 15

x - 5x = -15 +3

-4x = -12

x = -12/-4

x= 3

Hope it helps you

Answer 2

Answer:

Hi !!!

(x - 3)/(x - 3) = 5

1 = 5

But, If you cross multiply...

x - 3 = 5(x - 3)

x - 3 = 5x - 15

-12 = 4x

x = -3

(Mostly you cannot cross multiply as it is getting cancelled)

If the question is, (x - 3)/(x + 3) = 5

then, (x - 3) = 5(x + 3)

(x - 3) = 5x + 15

-3 - 15 = 5x - x

-18 = 4x

x = 9/2

whatever the symbol maybe just cross multiply if they are equated...
