Answer:
y = 2/5x - 2
Step-by-step explanation:
Subtract x to the other side to get -5y = -2x + 10. Divide -2x + 10 by -5 to get the answer.

Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
Consider the coordinate pair (4,y)
We observe that,
y can take any real values to lie on the graph of the equation.
As y really isn't a constant, we exclude it and take the equation as x=4
Answer:
86°
Step-by-step explanation:
Given:
A = (6x + 10)°
B = (4x +30)°
Two angles are supplementary if they sum up to 180° ;
A + B = 180°
Now insert the parameters and solve;
6x + 10 + 4x +30 = 180
10x + 40 = 180
10x = 140
x = 14
So;
B = (4x +30)° = 4(14) + 30 = 86°
