Question

How many solutions does the system of linear equations have?

y= x + 7

y = x - 8​

Answer 1

`\text{Find how many solutions are in the systems of equations}\\\\\text{Equal the equations to each other}\\\\x+7=x-8\\\\\text{Subtract x from both sides}\\\\7=-8\\\\\text{Since that's not true, there are no solutions}\\\\\boxed{\text{No solutions}}`
