What is 42= -7 × (z - 3)?
2 answers:
Answer:
z=3
Step-by-step explanation:
42=−7(z−3)
Simplify both sides of the equation.
42=−7(z−3)
42=(−7)(z)+(−7)(−3)(Distribute)
42=−7z+21
Flip the equation.
−7z+21=42
Subtract 21 from both sides.
−7z+21−21=42−21
−7z=21
Divide both sides by -7.
-7z/-7=21/7
z=3
Answer:
z=-3
