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.
