By solving given equations, the value of c is 30.
Given two equations
x + 2y = 10 and
3x + 6y = c
These lines represents the same line for some constant c.
Value of c:
x + 2y = 10-------------(1)
3x + 6y = c-------------(2)
Dividing equation (2) by 3
After solving the above equation, we get
x + 2y = c/3-----------(3)
Remember that a line is written as ax + by = c, in our case, both lines have a =1 and b = 2. Therefore, in orther that the two lines are equal, we need that, 10 = c/3
c = 10 × 3 = 30
c = 30
Therefore,
The value of c is 30.

Steps To Solve:
8y - 3 = бу + 17
~Subtract 8y to both sides
8y - 3 - 8y = бу + 17 - 8y
~Simplify
-3 = -2y + 17
~Subtract 17 to both sides
-3 - 17 = -2y + 17 - 17
~Simplify
-20 = -2y
~Divide -2 to both sides
-20/-2 = -2y/-2
~Simplify
10 = y

Hence, the answer is
