Answer 1

→Question: 2a + 4 = 0. Find the value of variable​?

↔Answer:

⇒Let's arrange variables on one side and constants on one sides.

⇒ 2a + 4 = 0

⇒ 2a = 0 -4

⇒ 2a = -4

⇒ a =  ⁻⁴⁄₂

⇒ a = -2

∴The value of variable is -2

⇔Verification:

⇔ 2a + 4 = 0

⇔ 2(-2) + 4 = 0

⇔ -4 + 4 = 0         ( - and + get cancelled)

⇔   0  =  0

∴ L.H.S = R.H.S

⇔Value of the variable is -2
