To solve the equation 7 = 3x-2 for x, what operations
1 answer:
X=3
Algebra is not one of my fav subjects in math but I do know this!
when solving what you do to one side you do to the other so
if 3x-2=7
the 2 is negative so you change that -2 into a positive
so add 2 to both sides
7+2=9
3x=9
now divide both sides by 3
X= 9/3 (nine over three)
now divide 9 by 3
9÷3=3
x=3
(Hope this helps!)
