Best ResponseYou've already chosen the best response.0u have y=43x. so u substitute the y in the 1st equation as 43x st: 11x + 3y = 20 > 11x + 3(43x) = 20 solve the new equation to get x

Best ResponseYou've already chosen the best response.0if u need to find both unknown. like in this case, after u get the x, substitute the value of x into any of the equation, then solve it to get the value of y.

Best ResponseYou've already chosen the best response.0You must understand what these equations represent. Suppose you are given two equations in this form and are asked to solve for x and y: 11x + 3y = 20  equation 1 3x + y = 4equation 2 Equations 1 and 2 represent two straight lines on a graph which has an x axis and a y axis. You are trying to find the point of intersection of these two lines on the graph. You can try it out using a graph paper and you will find the correct answer of the intersection point, namely (x,y)
