Question

6. Find the value of x. 7x 60° 5x​

Answer 1

Answer:

x = 30

Step-by-step explanation:

Simplifying

7x + -60 = 5x

Reorder the terms:

-60 + 7x = 5x

Solving

-60 + 7x = 5x

Solving for variable 'x'.

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

Add '-5x' to each side of the equation.

-60 + 7x + -5x = 5x + -5x

Combine like terms: 7x + -5x = 2x

-60 + 2x = 5x + -5x

Combine like terms: 5x + -5x = 0

-60 + 2x = 0

Add '60' to each side of the equation.

-60 + 60 + 2x = 0 + 60

Combine like terms: -60 + 60 = 0

0 + 2x = 0 + 60

2x = 0 + 60

Combine like terms: 0 + 60 = 60

2x = 60

Divide each side by '2'.

x = 30

Answer 2

Answer:

10

Step-by-step explanation:

7x+5x+60°=180°

12x=180°-60°

12x=120°

x=120/12

x=10
