Which values of P and Q result in an equation with no solutions? Qx+P=33x+25
Aleks04 [339]

The Equation is

Q x + P= 33 x+25

As both sides are equations in one variable , Comparing like terms of both sides gives,

→ Q x = 33 x

→ Q =33

And , P=25

But for this Equation to have no solution , Q must be equal to 33 and P should not be equal to 25.

Q=33,∧ P≠25 i.e any real number not equal to 25.P∈(-∞,∞)but P≠25

Find the values of x and y<br><br> 1-2i/ 2+i + 4-i/3+2i = x+iy
lina2011 [118]

Answer:

x=\frac{10}{13} and y=-\frac{24}{13}

Step-by-step explanation:

The given complex number equation is:

\frac{1-2i}{2+i}+\frac{4-i}{3+2i}=x+yi

We simplify the LHS and compare with the RHS

We collect LCD on the left to get:

\frac{(1-2i)(3+2i)+(4-i)(2+i)}{(2+i)(3+2i)}=x+yi

\frac{3+2i-6i+4+8+4i-2i+1}{6+4i+3i-2}=x+yi

Simplify to get:

\frac{16-2i}{4+7i}=x+yi

Rationalize the LHS:

\frac{(16-2i)(4-7i)}{(4+7i)(4-7i)}=x+yi

Expand the numerator using the distributive property and the denominator using difference  of two squares.

\frac{64-112i-8i-14}{16+49}=x+yi

Simplify to get:

\frac{50-120i}{65}=x+yi

\frac{10-24i}{13}=x+yi

\frac{10}{13}-\frac{24}{13}i=x+yi

By comparing real parts and imaginary parts; we have;

x=\frac{10}{13} and y=-\frac{24}{13}
