Triangle ABC

SO,

AB = AC +BC

x + 8 = 2x -5 + (BD + DC)

x + 8 = 2x-5 + 10 +14

x + 8 = 2x + 19

2x - x = -19 + 8

x = -11

X + 14 = 56 What would I do to both sides to answer this equation? O Multiply both sides by 14 © Subtract both sides by 14 Subtr

Lorico [155]

To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that

X + 14 - 14 = 56 - 14

X=42

Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.

Step-by-step explanation:

Given

Required

Find x

To find x, we make use of the following equivalent ratios:

$LN : LO = NK:OJ$

This gives:

$(x-3) : (x - 4) = (x +2) : (x)$

Convert to fractions

$\frac{x-3}{x-4} = \frac{x+2}{x}$

Cross Multiply

$x(x-3) = (x-4)(x+2)$

Open brackets

$x^2-3x = x^2 -4x +2x - 8$

Collect Like Terms

$x^2 - x^2-3x +4x -2x =- 8$

$-3x +4x -2x =- 8$

$-1x =- 8$

$-x =- 8$

Multiply through by -1

$-1 * -x =- 8*-1$

$x = 8$
