Question

check 15(x-1)+4(x+3)=2(7+x)

Answer 1

Answer:

Given, 15(x−1)+4(x+3)=2(7+x)

⟹ 15x−15+4x+12=14+2x ...[By Distribution Law]

⟹ 19x−3=14+2x ...[On simplifying]

⟹ 19x−2x=14+3 ...[Transposing x terms to one side]

⟹ 17x=17

⟹ x=1.

Answer 2

15(X+1)+4(X+3)=2(7+X)

15X+15+4X+12=14+2X

19X+27=14+2X

19X-2X=14-27

17X=-13

X=-13/17.
