How do you solve 8u-2=7u-4 ?

8u-2=7u-4

Step 1. Subtract 7u from both sides of the equation

8u-2-7u=7u-4-7u

u-2=-4

Step 2. Add 2 to both sides of the equation to solve for u.

u-2%2B2=-4%2B2

u=-2

Check...8u-2-7u=7u-4-7u...8%2A%28-2%29-2-7%2A%28-2%29=7%2A%28-2%29-4-7%2A%28-2%29...-32=-32...which is a true statement.

Step 3. ANSWER: Solution is u=-2

There is only one variable in this equation, u, so obviously you need to solve for it.
8u-2=7u-4
so subtract 7u from both sides
1u-2=-4
now add 2 to both sides
1u=-2
divide each side by one
u=-2
and thats all there is to it, u=-2
Hope that was helpful
