3x = 6y - 6
x = 2y - 2
4 ( 2y - 2 ) = 4 + 5 ( 2y - 2 )
8y - 8 = 4 + 10y - 10
2y = - 2
y = - 1
x = 2 ( - 1 ) - 2
x = - 4
i am a mathematics teacher. if anything to ask please pm me
Answer:
25 degrees
Step-by-step explanation:
In the picture attached, the lines and the angles are shown. There we can see that:
85° + 2x° + (x-10)° = 180°
75 + 3x = 180
x = (180 - 75)/3
x = 35°
∠3 and ∠(x-10)° are alternate interior angles, therefore they are congruent, so:
∠3 = x - 10
∠3 = 35 - 10
∠3 = 25°
Answer:
x = 10
Step-by-step explanation:
1. Add 4 to both sides of the equation
2. Simplify
3. Subtract x from both sided of the equation
4. Simplify
Therefore, x = 10
