Answer:
Step-by-step explanation:
x+1/2x=5-1/5x
combine like terms on left side
3/2x=5-1/5x
add 1/5x on both sides
17/10x=5
multiply by 10 on both sides to get rid of fraction
17x=50
divide 17 on both sides witch leaves
x=50/17

Answer:
<em>2 - 4i</em>
Step-by-step explanation:
Given the complex number 10/1+2i, to write this in the form a + bi, we will rationalize the function as shown;
= 10/1+2i * 1-2i/1-2i
= 10(1-2i)/(1+2i)(1-2i)
= 10-20i/(1-2i+2i-4i²)
= 10-20i/1-4(-1)
= 10-10i/1+4
= 10-20i/5
= 10/5 - 20i/5
= 2 - 4i
<em>Hence the expression in the form a + bi is 2 - 4i</em>
