Question

If you were to use the substitution method to solve

6x – y = 1
4x – 3y = –11

Choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation.

Answer 1

The substitution method:
y = 6 x - 1 ( the new equation )
After that:
4 x - 3 ( 6 x - 1 ) = -11
4 x - 18 x + 3 = - 14
- 14 x = - 14
x = 1, y = 6 * 1 - 1
y = 5
