Solve the linear equation 2.25 - 11j -7.75 +1.5j=0.5% -1.
j=-0.45
j=-0.25
j=0.25
j=0.45

9514 1404 393

  (a)  j = -0.45

Step-by-step explanation:

Maybe you want to solve ...

  2.25 - 11j -7.75 +1.5j=0.5j -1

Collecting terms gives ...

  -9.5j -5.5 = 0.5j -1

Adding 9.5j +1 to both sides, we get ...

  -4.5 = 10j

Dividing by 10 gives ...

  j = -0.45

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
