Someone will check your answers.
for these, the first step is to get all the x stuff on the left by itself by adding or subtracting. Then multiply or divide by x's coefficient so that you are left with just x:
x/5+6=10
subtract 6: x/5 = 4
multiply by 5: x = 4*5 = 20
x/5+6=10
subtract 6: x/5 = 4
multiply by 5: x = 4*5 = 20
