You can put this solution on YOUR website!
Solve -5%2Bx+=+20
When you are asked to solve a problem such as this, you are being asked to find the value of x that, when added to -5 will give the result of 20.
You can solve this equation for x this way:
-5%2Bx+=+20 To isolate the variable, x, you must add 5 to both sides of the equation. When you do this, you are "undoing" the -5 so that you are left with the variable by itself on the left side of the equation.
-5%2B5%2Bx+=+20%2B5 Because -5%2B5+=+0, we are left with x by itself on the left side:
x+=+20%2B5 ...and on the right side, you can see that 20%2B5+=+25 so...
highlight%28x+=+25%29
To see if this is really the correct solution for x, we'll substitute x+=+25 into the original equation to see if both sides are equal.
-5%2Bx+=+20 Substitute x+=+25%7D%0D%0A%7B%7B%7B-5%2B25+=+20 and, since -5%2B25+=+20 or 25-5+=+20 we have:
20+=+20
