Question

Which step could be used to help isolate the variable in the following equation

Answer 1

The subtraction of 4 on both sides would isolate the term 1.1j, then the division of 1.1 on both sides would isolate j.

Answer 2

Answer:

The steps required are subtract 4 both side and the divide both side by 1.1.

Step-by-step explanation:

Given : Equation $5.63-0.12 = 4 + 1.1j$

To find : Which step could be used to help isolate the variable in the following equation ?

Solution :

Equation $5.63-0.12 = 4 + 1.1j$

To isolate the variable,

Subtract 4 both side,

$5.63-0.12-4= 4+ 1.1j-4$

$5.63-0.12-4=1.1j$

Divide both side by 1.1,

$j=\frac{5.63-0.12-4}{1.1}$

Now we simplify it,

$j=\frac{1.51}{1.1}$

$j=1.37$

Therefore, the steps required are subtract 4 both side and the divide both side by 1.1.
