Combine like terms: First, let's simplify the equation by combining like terms on the right side.3−15c=−12c+2−17We combine the constants on the right side: 2−17=−15.So the equation becomes:3−15c=−12c−15
Move terms to one side: Next, we want to get all the terms with c on one side and the constants on the other side. Let's add 12c to both sides to move the c terms to the left side.3−15c+12c=−12c−15+12cThis simplifies to:3−3c=−15
Isolate the variable: Now, let's isolate the c term by moving the constant on the left side to the right side. We subtract 3 from both sides.3−3−3c=−15−3This simplifies to:−3c=−18
Find the value of c: To find the value of c, we divide both sides by −3.−3−3c=−3−18This gives us:c=6
