3x=4y-5 12y=9x+15 neeed help

3x = 4y - 5 --> 4y - 3x = 5 by rearranging ie. subtract 3x and add 5 to both sides. Call this equation 1. 12y = 9x + 15 --> 12y - 9x = 15 by subtracting 9x from both sides. Call this equation 2. Multiply equation 1 by 3 -->12y -9x = 15 which is the same as equation 2. Therefore there are multiple solutions for x and y related to the rule 12y - 9x = 15 or 4y - 3x = 5 Getting y by itself y = (3x + 5)/4 So for any x value the corresponding y value will be (3x + 5)/4 eg When x = 1, y = (3*1 + 5)/4 = 8/4 = 2
