Question

Explain the process to solve the equation. Use proper

Answer 1

1 - x = 4

To solve this we need x by itself,
to do that we have to put the one on the other side, we do this by adding the opposite of the number to both sides . The opposite of 1 is -1, when you add 1 + -1 on the left side of the equation you get 0 leavening -x alone. When you add -1 to the right side of the equation you get, 4-1 which is 3.
Now you are left with
-x =3
X cant be negative, so to get rid of the negative you have to divide the negative 1 on both sides. -1x / -1 = x
And 3/ -1 = 3
Now you are left with

X = -3
