What is 2 = 8 − 6/4x solved?

KengaRu [80]

Answer:

$x=4$

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: $2=2$

I need help with this how do I do it

Anna35 [415]

Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.

Add like terms to get 5x - 20 = 180
5x = 200
x = 40
