Answer 1

`\boxed{c.\:x\:=\:-3}` ✅

`\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}`

`(3x - 15)/(2) = 4x \\ ⇢ 3x - 15 = 4x * 2 \\ ⇢ 3x - 15 = 8x \\ ⇢ 3x - 8x = 15 \\ ⇢  - 5x = 15 \\ ⇢ x = (15)/( - 5) \\ ⇢ x = - 3`

`{ \bf{ \underbrace{To\:verify :}}}`

`(3x - 15)/(2) = 4x \\ ⇢  (3 * (- 3) - 15 )/(2) = 4 * - 3 \\ ⇢  ( - 9 - 15)/(2) = - 12 \\ ⇢  ( - 24)/(2) = - 12 \\ ⇢  - 12 = - 12 \\ ⇢ L.H.S.=R. H. S`

Hence verified.

Answer 2

X= - 3

Explanation:

Multiply both sides by 2 to remove the division on the LHS

3X - 15=8X

Move 3X to the RHS

-15 =8X - 3X

-15= 5X

Divide both sides by 5

-3 =X
