Answer:
y = 1/28
Step-by-step explanation:
Given the expression:
½y - 21/4 = 35/4
We'll have to Multiply through with the LCM which is (2y * 4 = 8y)
(8y) ½y - (8y) 21/4 = (8y) 35/4
4 - 2y * 21 = 2y * 35
4 - 42y = 70y
4 = 70y + 42y
4 = 112y
Divide through by 112 to make y the subject.
y = 4 / 112
y = 1 / 28
Answer: y = 28
Step-by-step explanation:
Add both sides by 21/4 to cancel out the 21/4 on the left side. 1/2y = 56/4
You can rewrite the fraction 56/4 as 28/2 by dividing the numerator and denominator by 2. 1/2y = 28/2
Multiply both sides by 2 and you get y = 28
