Unfortunately, you have left out the instructions for these problems. I'm assuming that your job is to find the value of x in each case.
6x+104=10x+60
Start by consolidating the "x" terms: 104 = 4x + 60.
Next, consolidate the constant terms: 104-60= 4x
Simplify: 44 = 4x
Solve for x: x = 11
You must check this result. Subst. 11 for x in the first given equation 6x+104=10x+60. Is the equation now true or false?
