Question

Pls answer to the questions below

​

Answer 1

Answer:

(Ⅰ) 5x - 7 = 2x + 8

→ 5x - 2x = 8 + 7

→ 3x = 15

→ x = 15/3

→ x = 5

(Ⅱ) x + ¾ = 5 ¾

→ x + ¾ = 5 × ¾

→ x + ¾ = 15/4

→ x = 15/4 - ¾

→ x = (15 - 3)/4

→ x = 12/4

→ x = 3

(Ⅲ) 5x - (3x - 1) = x - 4

→ 5x - 3x - 1 = x - 4

→ 2x + 1 = x - 4

→ 2x - x = - 4 - 1

→ x = - 5
