The value of d which will.make this system have the same solution is; d = 21/(3x -1)

First, we must make y, the subject of the formula in each case as follows;

  • y = (3x -1)/7. and
  • y = 3/d.

In essence, by equating y to y in both equations; we have;

  • (3x -1)/7 = 3/d

By Cross-product; we have;

  • (3x -1).d = 21

  • d = 21/(3x -1)

=12000(2.718281828459045)(0.65)

=22986

2nd Part:

=230000⋅(−0.044000000000000004⋅14)

=230000(2.718281828459045)(−0.616)

=124223
