Answer:
[tex]\boxed{\bold{One \ Solution}}[/tex]
Step-by-step explanation:
- Solve equation to find answer(s)
Combine: 6z - 3z = 3z
[tex]\bold{3z-7=-2+3}[/tex]
Add: -2 + 3 = 1
[tex]\bold{3z-7=1}[/tex]
Add 7 to both sides:
[tex]\bold{3z-7+7=1+7}[/tex]
Simplify:
[tex]\bold{3z=8}[/tex]
Divide both sides by 3:
[tex]\bold{\frac{3z}{3}=\frac{8}{3}}[/tex]
Simplify:
[tex]\bold{z=\frac{8}{3}}[/tex]
