Question

-3(4-x)=2x+5solve the following equation and check your result​

Answer 1

Answer:

-3(4-x)=2x+5

-12+3x=2x+5

-12-5  = 2x-3x

 -17    = -x

      x   = 17

checking the result

-3(4-x) = 2x+5

LHS = -3(4-17)                       RHS= (2×17) + 5

= (-3)×(- 13)                                     = 34 + 5

= 39                                                = 39

hence LHS   = RHS
