Question

Solve by the method of balancing an
equation and write the steps used to
separate the variable,
a) x + 7 = 10
b) 3x + 2 = 8​

Answer 1

a) X+7=10

=> X= 10-7 ( transposing from LHS to RHS )

=> X= 3

Verification:

3+7=10

Hence verified,.

X= 3

Answer: X=3

b) 3x+2= 8

=> 3x= 8-2 ( transposing from LHS to RHS)

=>3X= 6

=> X= 6÷3 ( transposing from LHS to RHS)

=> X= 2

Verification:

3× 2+2 = 8 ( according to BODMAS rule)

Hence verified,

X= 2

Answer:- X=2
