Answer:
There is a solution. Here's how:
Step-by-step explanation:
So, you work out the problem, and you lay it out here:
5-4+7+1=5-4+7x+1.
First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:
-4+7+1=-4+7x+1
Next, you add 4 to both sides, which makes you identify the identity.
Here's your equation now:
7+1=7x+1
Now, you subtract 1 from both sides.
Here's your equation now:
7=7x
Finally, divide both sides by 7, while identifying the identity.
x=1.
