Question

Solve the system using substitution . y =2x +4 , y = 2x - 6

Answer 1

No Solution

Explanation:

2x + 4 = 2x - 6

4 ≠ -6

If we subtract 2x from both sides we are left with a false stamens. That means there is no solution.

Answer 2

Systems

Both equations are solved for "y". Let's take one of them and plug it into the other one. I'll plug 2x + 4 instead of y in the second equation, y = 2x - 6.

y = 2x - 6

2x + 4 = 2x - 6

2x - 2x = -6 - 4

0x = -10

0 = -10

Since the statement is false, this system has no solutions.
