Solution - Adding, subtracting and finding the least common multiple
Step by Step Solution
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5/4-(-4*c+1/4)=0
Step by step solution :
Step 1 :
1
Simplify —
4
Equation at the end of step 1 :
5 1
— - (-4c + —) = 0
4 4
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 4 as the denominator :
-4c -4c • 4
-4c = ——— = ———————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-4c • 4 + 1 1 - 16c
——————————— = ———————
4 4
Equation at the end of step 2 :
5 (1 - 16c)
— - ————————— = 0
4 4
Step 3 :
5
Simplify —
4
Equation at the end of step 3 :
5 (1 - 16c)
— - ————————— = 0
4 4
Step 4 :
Adding fractions which have a common denominator :
4.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
5 - ((1-16c)) 16c + 4
————————————— = ———————
4 4
Step 5 :
Pulling out like terms :
5.1 Pull out like factors :
16c + 4 = 4 • (4c + 1)
Equation at the end of step 5 :
4c + 1 = 0
Step 6 :
Solving a Single Variable Equation :
6.1 Solve : 4c+1 = 0
Subtract 1 from both sides of the equation :
4c = -1
Divide both sides of the equation by 4:
c = -1/4 = -0.250
One solution was found :
c = -1/4 = -0.250How did we do?
