Solve the following linear equations: (i) 5x − 6 = 12 − x (ii) (iii) 5p + 7 = 19 − 2p (iv) (v) (vi)

Question

KnowledgeBoat · Accepted Answer

(i) We have: 5x − 6 = 12 − x ⇒ 5x + x = 12 + 6 [Transposing −x to LHS and −6 to RHS] ⇒ 6x = 18 ⇒ ∴ x = 3. (ii) We have: ∴ n = (iii) We have: 5p + 7 = 19 − 2p ⇒ 5p + 2p = 19 − 7 [Transposing −2p to LHS and +7 to RHS] ⇒ 7p = 12 ⇒ ∴ p = . (iv) We have: ∴ x = . (v) We have: ∴ x = 6. (vi) We have: ∴ y = 4.
