Answer: j = -0.45
Step-by-step explanation:
2.25 – 11j – 7.75 +1.5j = 0.5j – 1
We can group similar terms:
-11j +1.5j -0.5j = -1 - 2.25 + 7.75
-10j = 4.5
j = 4.5/-10
j = -0.45
Answer: j = -0.45
Answer:
j = − 0.45
Explanation:
2.25−11j−7.75+1.5j=0.5j−1
Step 1: Simplify both sides of the equation.
2.25−11j−7.75+1.5j=0.5j−1
2.25+−11j+−7.75+1.5j=0.5j+−1
(−11j+1.5j)+(2.25+−7.75)=0.5j−1(Combine Like Terms)
−9.5j+−5.5=0.5j−1
−9.5j−5.5=0.5j−1
Step 2: Subtract 0.5j from both sides.
−9.5j−5.5−0.5j=0.5j−1−0.5j
−10j−5.5=−1
Step 3: Add 5.5 to both sides.
−10j−5.5+5.5=−1+5.5
−10j=4.5
Step 4: Divide both sides by -10.
-10j/-10 = 4.5/-10
j = − 0.45
