Question

(5x + 4)° (8x – 710°

Answer 1

Answer:

x = 19

Step-by-step explanation:

Assuming the question was (5x + 4)° (8x – 71)°=180° not (5x + 4)° (8x – 710°,

Simplifying

(5x + 4) + (8x + -71) = 180

Reorder the terms:

(4 + 5x) + (8x + -71) = 180

Remove parenthesis around (4 + 5x)

4 + 5x + (8x + -71) = 180

Reorder the terms:

4 + 5x + (-71 + 8x) = 180

Remove parenthesis around (-71 + 8x)

4 + 5x + -71 + 8x = 180

Reorder the terms:

4 + -71 + 5x + 8x = 180

Combine like terms: 4 + -71 = -67

-67 + 5x + 8x = 180

Combine like terms: 5x + 8x = 13x

-67 + 13x = 180

Solving

-67 + 13x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '67' to each side of the equation.

-67 + 67 + 13x = 180 + 67

Combine like terms: -67 + 67 = 0

0 + 13x = 180 + 67

13x = 180 + 67

Combine like terms: 180 + 67 = 247

13x = 247

Divide each side by '13'.

x = 19

Simplifying

x = 19
