Q. What value of c is a solution to this equation?c−4=1
Identify Goal: Identify the goal of the problem.The goal is to find the value of c that makes the equation c−4=1 true.
Isolate Variable: Isolate the variable c on one side of the equation.To do this, we need to get rid of the −4 that is being subtracted from c. We can do this by adding 4 to both sides of the equation.c−4+4=1+4
Perform Addition: Perform the addition on both sides of the equation.c−4+4=c1+4=5So, the equation simplifies to c=5.
Check Solution: Check the solution by substituting the value of c back into the original equation.Substitute c=5 into c−4=1.5−4=11=1The left side of the equation equals the right side, which means c=5 is the correct solution.
