Question

MCQ find
in the equation 3 x = 4 - x transposing -x to LHS we get
a. 3x-x=4
b. 3x+x=4
c. -3x+x=4
d. -3x-x=4​

Answer 1

Answer:-

answer is option b 3x+x= 4

Step-by-step explanation:-

3x= 4-x

when we transfer a variable from LHS to RHS or from RHS to LHS  the sign is changed  if it is +ve it converted into -ve or  -ve into +ve

therefore we get 3x+x=4

Answer 2

Answer:

$we \: have \: to \: transpose \: - x \: to \: \: lhs \: .... \\ \therefore - x = x \\ \therefore \: 3x + x = 4 \\ \\ \red{\therefore \: new \: equation \: becomes \: = 3x + x = 4} \\ </p><p>\green{\therefore \: option \:( b )\: .is \: correct}</p><p></p><p></p><p>$
