Answer:
because this is a parallelogram
=> b - 10 + b + 10 = 180
<=> 2b = 180
=> b = 90
with b = 90 => b - 10 = 80
b + 10 = 100
we also have:
d = b + 10 => d = 100
c = b - 10 => c = 80

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
