Question

Solve each of the following equations and check your answers:
10 − y = 6

Answer 1

10 − y = 6
Subtracting 10 from both sides, we get
⇒ 10 − y − 10 = 6 − 10
⇒ −y = −4.
⇒ Multiplying both sides by −1, we get
⇒ −y $\times$−1 = −4 $\times$−1
⇒ y = 4
Verification:
Substituting y = 4 in LHS, we get
LHS = 10 − y = 10$-$4 = 6 and RHS = 6
LHS = RHS
Hence, verified.
