Divide 7 by 9 and you’ll get your answer in a calculator
4x-10=2x subtract 2x from both sides
2x-10=0 add 10 to both sides
2x=10 divide both sides by 2
x=5
Now I don’t know how to do this but I would recommended a tutor for you
Step 1: Simplify both sides of the equation.
17−2n=9
17+−2n=9
−2n+17=9
Step 2: Subtract 17 from both sides.
−2n+17−17=9−17
−2n=−8
Step 3: Divide both sides by -2.
−2n−2=−8−2
n=4
