Question

Which step could be used to help isolate the variable in the following equation? 5.6j – 0.12 = 4 + 1.1j

Answer 1

Answer:

$j=206/225$

Step-by-step explanation:

we have

$5.6j-0.12=4+1.1j$

Solve for j

That means-----> Isolate the variable j

step 1

Subtract 1.1j both sides (Subtraction Property of Equality)

$5.6j-0.12-1.1j=4+1.1j-1.1j$

$4.5j-0.12=4$

step 2

Adds 0.12 both sides (Addition Property of Equality)

$4.5j-0.12+0.12=4+0.12$

$4.5j=4.12$

step 3

Divide by 4.5 both sides (Division Property of Equality)

$4.5j/4.5=4.12/4.5$

$j=4.12/4.5$

Convert to fraction number

Multiply by 100 both numerator and denominator

$j=412/450$

simplify

$j=206/225$

Answer 2

Answer:

Subtract 1.1j from both sides.
