Answer:
4 x + 5 = 2 x + 2 x + 5
Step-by-step explanation:
If we simplify the following equation it will be 4 x + 5 = 4 x + 5. This equation has infinitely many solutions because every value for x we substitute in, it will be the same on both sides, for example
Substitute x = 7 into 4 x + 5 = 4 x + 5
4 × ( 7 ) + 5 = 4 × ( 7 ) + 5
28 + 5 = 28 + 5
33 = 33
Every x value that we substitute in will result in the equation having the same result on both sides
