Help me please, thanks.<br><br> -Tornado

Answer:

$x = - \frac{25}{3}$

Step-by-step explanation:

$\frac{10}{3} = \frac{x}{( - \frac{5}{2}) }$

<h3>i) simplify the complex fraction</h3>

$\frac{10}{3} = - \frac{2x}{5}$

<h3>ii) simplify the equation using cross multiplication</h3>

$5(10) = - 2x(3)$

$50 = - 6x$

<h3>iii) swap the sides of the equation</h3>

$- 6x = 50$

<h3>iv) divide both sides of the equation by -6</h3>

$\frac{ - 6x}{ - 6} = \frac{50}{ - 6}$

$x = - \frac{50}{6}$

<h3>v) simplify the fraction</h3>

$x = - \frac{25}{3}$

90 x= 81 + 25 <br> I need help ?

charle [14.2K]

Answer:

$x = \frac {53} {45}$

Step-by-step explanation:

<u>Step 1: Combine on the right side </u>

$90x = 81 + 25$

$90x = 106$

<u>Step 2: Divide both sides by 90 </u>

$\frac {90x} {90} = \frac {106} {90}$

$x = \frac {106/2} {90/2}$

$x = \frac {53} {45}$

Answer: $x = \frac {53} {45}$
