<u> x = 3.5y </u><u>equation shows the number of teaspoons of sugar, y, needed to make </u><u>x tarts.</u>
What is the linear equation in two variable?
Any equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers, and a and b are not both zero, is called linear equation in two variable.
<u>According to the given question</u>
A recipe require 3.5 teaspoons of sugar to make a tart.
y represents the number of teaspoons of sugar.
x represents the number of tarts.
Now, for x tart 3.5y teaspoons of sugar required.
⇒ x = 3.5y
Hence, the linear equation in two variable that shows the number of teaspoons of sugar y, needed to make x number or tarts is x = 3.5y.
