(5x+6) over 2 = 3 (4x+12)

Mathematics
1 answer:
Nana76 [90]4 years ago
6 0

x= -66/19

Multiply 2 on both sides:

2*(5x+6)/2=3(4x+12)*2

Simplify:

5x+6=24x+72

Subtract 6 from both sides:

5x+6-6=24x+72-6

Simplify:

5x=24x+66

Subtract 24x from both sides:

5x-24x=24x+66-24x

Simplify:

-19x=66

Divide both sides by -19

-19x/-19=66/-19

Simplify:

x= -66/19

  • Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

Leg <em>a</em> = <em>x</em>

Leg <em>b</em> = 64

Hypotenuse <em>c</em> = 80

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute:                    x² + 64² = 80²
  2. Isolate <em>x</em> term:              x² = 80² - 64²
  3. Exponents:                   x² = 6400 - 4096
  4. Subtract:                       x² = 2304
  5. Isolate <em>x</em>:                       x = √2304
  6. Evaluate:                       x = 48

Mid point formula

(x1 + x2) , (y1+y2)
---------      --------
    2             2
Thus for x it would be (6+(-2)) /2 or 4/2 or 2.
For y (-4 + 4) / 2 or 0 / 2  or  0.
Mid point is (2,0)
