3(4u - 2) = -30: Given equation
Step 1:
12u - 6 = -30: Distributive property
Explanation:
[tex]\begin{gathered} 3(4u-2)=-30 \\ 3\cdot4u-3\cdot2=-30 \\ 12u-6=-30 \end{gathered}[/tex]
Step 2:
12u -6 + 6 = -30 + 6: Addition property of Equality
Explanation: This step is required to eliminate the term -6 from the left side.
Step 3:
12u = -24: Simplifying
Explanation: Here we just solved the arithmetic operations -6 + 6, on the left side, and -30 + 6, on the right side.
Step 4:
12u/12 = -24/12: Division property of the Equality
Explanation: This step is required to isolat the term u on the left side.
Step 5:
u = -2: Simplifying
Explanation: Here, we just sulvet the arithmetic operations 12/12, on the left side, and -24/12, on the right side.
