$x=4$

General Formulas and Concepts:

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

$2=8-\frac{6}{4} x$

Step 2: Solve for x

Subtract 8 on both sides: $-6=-\frac{6}{4} x$
Divide both sides by -6/4: $4=x$
Rewrite: $x=4$

Step 3: Check

Plug in x to verify it's a solution.

Substitute: $2=8-\frac{6}{4}(4)$
Multiply: $2=8-6$
Subtract: $2=2$

Vladimir79 [104]

Answer:

Step-by-step explanation:

<h2>Ratios </h2>

16 is to 10 as what number is to 25

this makes use of ratios

16 : 10

x : 25

hence we can make use of cross multiplication

10x = 16 * 25

10x = 400

x = 40

<h3>the number is 40</h3>

A. 25-3x=40
3x=40-25
3x= 15
X = 5
B.1/3(x-10)=-4
1/3x - 10/3 = -4
1/3x = -4 + 10/3
X= -2/3
