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 :
y-4/3-(11/3)=0
Step by step solution :
Step 1 :
11
Simplify ——
3
Equation at the end of step 1 :
4 11
(y - —) - —— = 0
3 3
Step 2 :
4
Simplify —
3
Equation at the end of step 2 :
4 11
(y - —) - —— = 0
3 3
Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 3 as the denominator :
y y • 3
y = — = —————
1 3
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 :
3.2 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:
y • 3 - (4) 3y - 4
——————————— = ——————
3 3
Equation at the end of step 3 :
(3y - 4) 11
———————— - —— = 0
3 3
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:
(3y-4) - (11) 3y - 15
————————————— = ———————
3 3
Step 5 :
Pulling out like terms :
5.1 Pull out like factors :
3y - 15 = 3 • (y - 5)
Equation at the end of step 5 :
y - 5 = 0
Step 6 :
Solving a Single Variable Equation :
6.1 Solve : y-5 = 0
Add 5 to both sides of the equation :
y = 5
One solution was found :
y = 5How did we do?
