(1-6i)(-5-8i)\\(1)(-5)+(1)(-8i)+(-6i)(-5)+(-6i)(-8i)\\-5-8i+30i+48i^2\\-5+22i+48(-1)\\-5+22i-48\\-53+22i

A complete table with values for x or y that make this equation true:3x+y=15
Andreyy89

Answer:


Step-by-step explanation:

The given equation is: 3x+y=15,

Now, putting x=2 in above equation,

3(2)+y=15

y=15-6=9

Now, put y=3 in the given equation,

3x+3=15

3x=12

x=4

Putting x=6,

3(6)+y=15

y=15-18y=-3

Putting x=0,

0+y=15

y=15

Putting x=3,

3(3)+y=15

y=15-9

y=6

Putting y=0,

3x+0=15

x=5

Putting y=8,

3x+8=15

3x=7

x=\frac{7}{3}
