Question

solve the following equation 15 = 7 + 2( + 4 )​

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

Step-by-step explanation:

15=7+2(+4)

15=9(+4)

15does not equal36

therefore L.H.S does not equal to R H.S
