Question 223758
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+2=-4+2}}}


{{{u=-2}}}


Check...{{{8u-2-7u=7u-4-7u}}}...{{{8*(-2)-2-7*(-2)=7*(-2)-4-7*(-2)}}}...{{{-32=-32}}}...which is a true statement.


Step 3.  ANSWER:  Solution is {{{u=-2}}}


I hope the above steps were helpful.
