Mai says that the equation 2x+2=x+1 has no solutions because the left side is double the right side. do you agree with mai provide evidence for your reasoning.

No, Mai needs to solve the problem.

Step-by-step explanation:

2x+2=x+1 - subtract 2 from both sides

2x=x-1 - subtract x from both sides

x= -1 - solution

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
