Topics Terms and topics;Answer (1 of 5) When you get deeper into algebra, you'll start applying the word "function" differently At first, you always look at the representation and try to express y in terms of x Then you look at the result and decide if each xvalue used maps to only one y4x 12y = 64 Now both equations have "4x" in them, so if we subtract one from the other we will get rid of the x's and be left with just y's 4x y = 25 MINUS 4x 12y = 64 EQUALS 13y = 39 We then divide both sides of the equation to find what y equals y = 39/13 = 3

x = 1 y = 2 Solving By Elimination 12x 7y = 2 8x 11y = 30 First, let's have a look at our system and recall what the elimination method is To eliminate a variable (either x or y), we have to multiply the different equations in the system to get the least common multiple One equation must be positive and the other negative to cancel each other out The least common multiple of Find the equation of a straight line through the intersection of lines 5x – 6y = 2, 3x 2y = 10 and perpendicular to the line 4x – 7y 13 = 0 asked in Coordinate Geometry by nchi ( 4k points) Prove that the equation 2x 2 5xy 3y 2 6x 7y 4 = 0 represents a pair of straight lines Find the coordinates of their point of intersection and also the angle between them straight line;
