    An equation is shown below: 9(3x – 16) + 15 = 6x – 24 Part A: Write the steps you will use to solve the equation, and explain each step. (6 points) Part B: What value of x makes the equation true? (4 points) @pooja195

    Step 1: Simplify both sides of the equation. 27x−144+15=6x−24 Simplify: (Hide steps) Let's simplify step-by-step. 27x−144+15=6x−24 27x+−144+15=6x+−24 (27x)+(−144+15)=6x−24(Combine Like Terms) 27x+−129=6x−24 27x−129=6x−24 Step 2: Subtract 6x from both sides. 27x−129−6x=6x−24−6x 21x−129=−24 Step 3: Add 129 to both sides. 21x−129+129=−24+129 21x=105 Step 4: Divide both sides by 21.
