Question

To solve the equation 7 = 3x-2 for x, what operations

Answer 1

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!)
