Question

Solve for x and show your work! For each equation choose if there are:

• zero solutions for x • exactly one solution for x • or an infinite number of solutions for x.
3x + 5 = 7 + 3x


2(3x + 9) = 18 + 6x

Answer 1

3x+5=7+3x 2(3x+9)=18+6x
-3x -3x 6x+18=6x+18
—————- -6x -6x
5=7 ———————
-5 -5 18=18
—————— -18 -18
0=2 —————
Zero solution 0=0
An infinite number of solution
