Um which variable are u trying to isolate ?
misty1212
  • misty1212
\(x\) is a variable it can be anything
misty1212
  • misty1212
if you want to solve \[7x+7=4y\] for \(x\) your answer will have a \(y\) in it \[7x+7=4y\\ 7x=4y-7\\ x=\frac{4y-7}{7}\]

solve \[7x+7=112\] for \(x\)
misty1212
  • misty1212
subtract 7 get \[7x=105\]
misty1212
  • misty1212
divide by 7 get \[x=105\div 7=15\]
