8y-10=6y-2 help me please I don't get this

murzikaleks [220]

$8y-10=6y-2$

$8y-10=6y-2:y$ $| Solve \ for \ y|$

$8y=6y-2+10
 
$ $|Add \ 10 \ to \ both \ sides|$

$
8y=6y+8
 
$

$
8y-6y=8
 
$ $|Subtract \ 6y \ from \ both \ sides|$

$2y=8$

$y=8/2$ $|Divide \ both \ sides \ by \ 2|$

$y=4$

$\star \ Hence \ solved$

Solve the following new equation

mixer [17]

Answer:

<h3>x = 1.54 or x = - 4.54 to 2 decimal places</h3>

Step-by-step explanation:

x² + 3x - 7 = 0

Using the quadratic formula

a = 1 b = 3 c = - 7

$x = \frac{3 ± \sqrt{ {3}^{2} - 4(1)( - 7) } }{2(1)} \\ x = \frac{ - 3± \sqrt{9 + 28} }{2} \\ \\ x = \frac{ -3 ± \sqrt{37} }{2} \\ \\ x = \frac{ - 3 + \sqrt{37} }{2} \: \: \: \: \: or \: \: \: x = \frac{ - 3 - \sqrt{37} }{2} \\ \\ x = 1.54 \: \: \: or \: \: x = - 4.54$

Hope this helps you
