Solution - Linear equations with one unknown
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 :
2*(3*y+5)-(3*(5*y+1/3))=0
Step by step solution :
Step 1 :
1
Simplify —
3
Equation at the end of step 1 :
1
(2 • (3y + 5)) - (3 • (5y + —)) = 0
3
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 3 as the denominator :
5y 5y • 3
5y = —— = ——————
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 :
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:
5y • 3 + 1 15y + 1
—————————— = ———————
3 3
Equation at the end of step 2 :
(15y + 1)
(2 • (3y + 5)) - (3 • —————————) = 0
3
Step 3 :
Equation at the end of step 3 :
(2 • (3y + 5)) - (15y + 1) = 0
Step 4 :
Equation at the end of step 4 :
2 • (3y + 5) - (15y + 1) = 0
Step 5 :
Step 6 :
Pulling out like terms :
6.1 Pull out like factors :
9 - 9y = -9 • (y - 1)
Equation at the end of step 6 :
-9 • (y - 1) = 0
Step 7 :
Equations which are never true :
7.1 Solve : -9 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
7.2 Solve : y-1 = 0
Add 1 to both sides of the equation :
y = 1
One solution was found :
y = 1How did we do?
