Answer:
2. One solution
Explanation:
one solution because
3x - 2 = 3x + 5
here you group like terms so the x’s will be grouped at one place and the numbers without variables will also be grouped at one place
so
3x -3x = 5+2
the 3x became negative because it crossed the equal to sign
so
3x-3x=5+2
0x=7
so x=7
