Solve the equation for x. 3x - 5x+ 5 = 20

Hey there!

3x - 5x + 5 = 20

• First COMBINE your LIKE TERMS

(3x - 5x) + (5) = 20

3x - 5x = -2x

• NEW EQUATION:

-2x + 5 = 20

• SUBTRACT by 5 on BOTH SIDES

Like: -2x + 5 - 5 = 20 - 5

Cancel out: 5 - 5 because that gives you a 0

Keep; 20 - 5 because it helps us solve for your x

**20 - 5 = 15**

• NEW EQUATION:

-2x = 15

• DIVIDE by -2 on BOTH SIDES

2x/-2 = 15/-2

Cancel out: -2x/-2 because that gives you 1

Keep: 15/-2 because it helps us solve for x (it also gives the value of “x”)

**AFTER SOLVING ABOVE WE FOUND OUR ANSWER**

x = -15/2 ✅

Good luck on your assignment and enjoy your day!

step-by-2step explanation:

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
