Question

Solve the system of equations. y=x+2 4x-4y= 1

Answer 1

Answer:

No solution

Step-by-step explanation:

1. 4x - 4y = 1
2. 4x - 4(x + 2) = 1
3. 4x - 4x - 8 = 1
4. - 8 = 1

Our end result is -8 = 1. This is not true, so this system of equations have no solution.

Answer 2

Answer:

No solutions

Step-by-step explanation:

Step 1: Substitute x + 2 for y in 4x - 4y = 1.

• $4x-4(x+2)=1$
• $4x+(-4)(x)+(-4)(2)=1$
• $4x-4x-8=1$
• $-8 = 1$  (simplify both sides)
• $-8+8=1+8$
• $0\neq 9$

Thus, the answer is no solutions.
