The first = x => the second = x + 4
Sum = x + (x+4) = 56
2x + 4 = 56
2x = 52
x = 26 - the first => the second = 30

You always want the period to the right of the first number meaning you’ll start from there counting backwards because it is negative.

Which of the following is the quotient of the rational expression shown below 2x+5/3x /2x-1/2x+1

svet-max [94.6K]

$\frac{2x + 5}{3x} \div \frac{2x - 1}{2x + 1} = \frac{2x + 5}{3x} \times \frac{2x + 1}{2x - 1} = \\ = \frac{ (2x + 5)(2x + 1)}{3x(2x - 1)} = \frac{ {4x}^{2} + 12x + 5 }{6 {x}^{2} - 3x}$

Find the complex number to solve the equation: 9(2-4i) - 6(x+yi) = 14-3i

tester [92]

$9(2-4i)-6(x+yi)=14-3i\\
18-36i-6x-6yi=14-3i\\
-6x-6yi=-4+33i\\
-6x=-4 \wedge -6y=33\\
x=\dfrac{4}{6} \wedge y=-\dfrac{33}{6}\\
x=\dfrac{2}{3} \wedge y=-\dfrac{11}{2}\\\\
\boxed{x+yi=\dfrac{2}{3}-\dfrac{11}{2}i}$
