Y = 8x + 10
y = 2
whats the substitution ?

8x + 3y = 11 (1)

3x - y = 2 (2)

In equation (2) it is easy to express y in terms of x

3x - y = 2

3x - 2 = y

Substituting y = 3x - 2 in equation (1) we get,

8x + 3y = 11

8x + 3(3x - 2) = 11

8x + 9x - 6 = 11

17x - 6 = 11

17x = 11 + 6

17x = 17

x = 17/17

x = 1

Now, substituting value of x = 1 in equation (2)

Hence,

3x - y = 2

y = 3x - 2

y = 3 x 1 - 2

y = 3 - 2

y = 1

Therefore,x = 1 and y = 1 is the solution of the given equation.
