-15 is in fact less than -7. Here is a number line:
-15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5...
Let me know if you need clarification :)
4 - 5x = 59
Subtract 4 from both sides:
-5x = 55
Since x is being multiplied by -5, the next step is to divide both sides by -5.
i Think all are correct not sure tho
