Question

Fred and ethyl had 132 flowers altogether at first. After Fred sold 1/4 of his flowers and Ethyl sold 48 of her flowers, they had the same number of flowers left. How many did they each have at first?

Answer 1

F + E = 132
3/4 F = E - 48           ( after Fred sold 1/4 of his flowers there is 3/4 flowers left )
--------------------
E = 132 - F
3/4 F = 132 - F - 48
3/4 F + F = 84
7/4 F = 84
F = 84 : 7/4 = 84 * 4/7 = 48
E = 132 - 48 = 84
We can prove it: 3/4 * 48 = 84 - 48
36 = 36 ( correct )
Answer:
Fred had 48 flowers and Ethel 84 flowers.

Answer 2

Fred had 48 flowers.

Ethyl had 84 flowers.

Further explanation

Simultaneous Linear Equations could be solved by using several methods such as :

• Elimination Method

• Substitution Method

• Graph Method

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

Let :

Number of Fred's Flowers = f

Number of Ethyl's Flowers = e

Fred and ethyl had 132 flowers altogether at first.

$f + e = 132$

$f = 132 - e$ → Equation 1

After Fred sold 1/4 of his flowers and Ethyl sold 48 of her flowers, they had the same number of flowers left.

$f - \frac{1}{4}f = e - 48$

$\frac{3}{4}f = e - 48$

$\frac{3}{4}(132 - e) = e - 48$ ← Equation 1

$\frac{3}{4}(132) - \frac{3}{4}e = e - 48$

$99 + 48 = \frac{3}{4}e + e$

$147 = \frac{7}{4}e$

$e = 147 \div \frac{7}{4}$

$e = \boxed{84}$

$f = 132 - e$

$f = 132 - 84$

$f = \boxed {48}$
