Answer:
The value of x is -4/5.
Step-by-step explanation:
First, you have to get rid of brackets, by expanding out :
2(6x+10) - 3x = 10 - (x-2)
2(6x) + 2(10) - 3x = 10 - x + 2
12x + 20 - 3x = 10 - x + 2
Next, is to bring all the x variable to one side :
12x + 20 - 3x = 10 - x + 2
12x - 3x + x = 10 + 2 - 20
10x = -8
Lastly, is to solve it by dividing 10 to both sides :
10x = -8
10x ÷ 10 = -8 ÷ 10
x = -4/5
Answer:
x=12°
Step-by-step explanation:
180 - 90 = 4x - 2° + 3x + 8 °
90°= 7x + 6
90° - 6 = 7x
7x = 84
x= 84/7
x = 12
