Answer:
122+4x=3x+87
the first step is to move the variable and constants because we can not add variable and constants together we will move 3x and 122 it will be something like this: 3x-4x=122-87 now that the constants and variables have moved we can solve it because we moved them the addition symbol will become a subtraction symbol the answer will be: 1x=35
Explanation:
122+4x=3x+87
3x-4x=122-87
1x=35
