Answer:
-7
Step-by-step explanation:
2x + 3 = x - 4
so you first add four to both sides of the equal sign:
2x + 3 = x - 4
+ 4 + 4
making the equation:
2x + 7 = x
you now subtract 2x from both sides:
2x + 7 = x
-2x - 2x
to get:
7 = -1x
you then divide both sides by -1:
7/-1 = -1x/-1
to get:
-7 equals x or x = -7
