How do you solve 4x plus 3y equals 90? - Answers

We have two unknown and only one known. This mean that we need to set a fixed value to one unknown and we can calculate the other. Example: 4x+3y=90 we say that X = 15 then the question is: 4*15+3y=90 We simplify: 3y=90-4*15 3y=90-60 3y=30 We divide by 3 on both sides of equal. y=10 By this we know that if x=15 then y must be 10 for the result to be 90. When dealing with 2 unknown we normally use the X and Y values in order to draw a graph.
