4 +42x - 1) = 12 what are the solutions

x = 2

Step-by-step explanation:

Simplifying

4(2x + -1) = 12

Reorder the terms:

4(-1 + 2x) = 12

(-1 * 4 + 2x * 4) = 12

(-4 + 8x) = 12

Solving

-4 + 8x = 12

Solving for variable 'x'.

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

Add '4' to each side of the equation.

-4 + 4 + 8x = 12 + 4

Combine like terms: -4 + 4 = 0

0 + 8x = 12 + 4

8x = 12 + 4

Combine like terms: 12 + 4 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the square root of what number? if you add that, then someone will probably answer the question.
