Question

Can anyone become my math tutor please?



4x + 2x − 7 = 3x − 7

Answer 1

Start off by combining like terms so 4x+2x=6x

6x-7=3x-7
Minus 3x from both sides
3x-7=-7
Add 7 to both sides (using inverse operations)
Since -7 and 7 cancel each other it’s 0
3x=0
3 3 Divide by 3

Your answer is 0

Answer 2

3x=0 or x=0

Explanation:

4x+2x-7=3x-7

4x+2x=3x

6x=3x

6x-3x=0
