Question

solve the following equations by the systematic method and also verify the answer. x-7= –6​

Answer 1

Answer:

Given x−7=6

⇒x−7+7=6+7[Adding 7 to both sides]

⇒x=13

Verification:

Substituting x=13 in equation x−7=6

We get

x−7=6

⇒13−7=6

⇒6=6

∴LHS=RHS, when x=13

Answer 2

Answer:

x = 1

Step-by-step explanation:

= x - 7 = - 6

= x = - 6 + 7

= x = 1

Verifying the answer:

Put x = -1 in the given equation

= x - 7 = - 6

= 1 - 7 = - 6

= - 6 = - 6

= L.H.S = R.H.S

Hence Verified.
