Answer:
Step-by-step explanation:
Step 1: Factor left side of equation.
(c+1)(c+9)=0
Step 2: Set factors equal to 0.
c+1=0 or c+9=0
c=−1 or c=−9
C= -1 OR C= -9
Steps to solving equations:
Simplify/combine the like terms
Isolate the variable (Get the variable on one side
Solve for the variable
-2y - 7 + 5y = 13 - 2y Simplify/Combine terms
3y -7 = 13 - 2y Isolate variable by adding 2y to both sides
5y - 7 = 13 Add 7 to both sides to get y alone on one side
5y = 20 Divide by 5 on both sides to solve for y
y = 4
You can check your answer by replacing y with 4 in the original equation.
