Answer:
x= -7
Step-by-step explanation:
To solve this equation, we want to find out what x is. We have to get x by itself.
Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.
2x+3=x-4
x is being added to -4. The opposite of addition is subtraction. Subtract x from both sides.
2x-x+3=x-x-4
2x-x+3= -4
x+3= -4
3 is being added to x. The opposite of addition is subtraction. Subtract 3 from both sides.
x+3-3= -4-3
x= -4-3
x=-7
Let's check our solution. Plug -7 in for x in the original equation.
2x+3=x-4
2(-7)+3= -7-4
-14+3= -7-4
-11= -11
Both sides are the same, so we know that -7 is the solution.
