Answer:

$\Huge\boxed {x = 15}$

Step-by-step explanation:

⟾Collect like terms

8x - 10x = x - 45

⟾Move the variable to the left

- 2x = x - 45

⟾Collect like terms again

- 2x - x = - 45

⟾Divide both sides by -3

- 3x = - 45

⟾ x = 45 ÷ 3

x = 15.

What is the value of x? Enter your answer in the box. x = ___

lapo4ka [179]

Answer:

x=8

Explanation:

The picture tells us that the triangle is equilateral (this means that each angle is 60°). We can assume this because each side has been marked with the same line.

Because each angle is equal to 60°, this means that:

7x+4=60

Now solve for x:

7x=56
x=8
