2 answers:

7 0

Explained --------A one-variable equation is an equation that has exactly one variable in it. Similarly, a one-variable inequality is an inequality that has exactly one variable in it. Setting up one-variable equations and inequalities is an extremely useful tool in mathematics.

Answer:

The steps to doing this are as follows:

1. Identify the unknown and represent it with a variable.

2. Set up an equation or inequality using that variable.

3. Solve the equation or inequality to find an answer to the problem.

2.2x+3y=15.25 4.6x+2.1y=18.325 USING ELIMINATION SHOW WORK PLEASE

Artist 52 [7]

-4.6(2.2x+3y=15.25) = -10.12x - 13.8y = -70.15

2.2(4.6x+2.1y=18.325) = 10.12x - 4.62y = 40.315

simplify

-4.62y = -29.835

divide both sides by -4.62 to isolate y

y= 6.46

2.2x + 3 (6.46) = 15.25

2.2x + 19.38 = 15.25

subtract 19.38 to both sides

2.2x = -4.3

divide 2.2 to both sides

x= -1.95

I hope that this helped :)

Answer:

Therefore the value of x is

$x=1\pm\sqrt{19}i$

Step-by-step explanation:

Given:

$x^{2}+20=2x$ which is

$x^{2}-2x+20=0$

To Find:

x = ? using Quadratic Formula

Solution:

For a Quadratic Equation ax² + bx + c = 0 , Formula Method is given as

$x=\dfrac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

On Comparing with above we get

$a=1\\b=-2\\c=20$

Substituting a , b , c in Formula method we get

$x=\dfrac{-(-2)\pm\sqrt{(-2)^{2}-4(1)(20)}}{2\times 1}\\\\x=\dfrac{2\pm\sqrt{-76}}{2}\\\\x=\dfrac{2\pm2\sqrt{19}i}{2}\\Dividing\ by\ 2\ we\ get\\\\x=1 \pm\sqrt{19}i$

Therefore the value of x is

$x=1\pm\sqrt{19}i$
