SalmonWorldTopper

Step-by-step explanation:

a⟩. (4x - 1)/2 = x + 7

⇛(4x - 1)/2 = (x+7)/1

By doing cross multiplication, we get

⇛1(4x - 1) = 2(x + 7)

⇛4x - 1 = 2x + 7

⇛4x - 2x = 7-1

⇛2x = 6

⇛x = 6÷2 = 6/2

∴ x = 3 Ans.

b⟩. 3x + 2 = (2x + 13)/3

⇛(3x + 2)/1 = (2x + 13)/3

⇛3(3x + 2) = 1(2x + 13)

⇛9x + 6 = 2x + 13

⇛9x - 2x = 13-6

⇛7x = 7

⇛x = 7÷7 = 7/7

∴ x = 0 = 1 Ans.
