I would think this is many solutions, the reason is because, there is no specific answer (y) so, x could be anything because it would have to equal to y, which could also be anything! I hope im right! Sorry if im wrong!
Given equation :
.
Strategy 1: We can cross mutiply both sides remove fraction form.
On cross multiplication, we get
x * 7 = 3 * 42
7x = 126.
Dividing both sides by 7, we get
<h3>
x = 18.</h3>
Strategy 2: We can find least common denominator(lcd) of both sides and multiplying both sides by that lcd to get rid denominators from both sides.
LCD of 42 and 7 is 42.
Therefore, multiplying both sides by 42, we get

x = 6 * 3
<h3>x = 18.</h3>
Answer:
B)
Step-by-step explanation:
Total amount of money paid
=11 x 15
=$165
total amount of money sold
=25 x 15
=$375
difference
= 375 - 165
=$210
