3x-4y=7,5x+2y=3 slove graphically |
| Answer» {tex}3x - 4y = 7\\ and\\ 5x + 2y = 3{/tex}The given system of linear equation is {tex}3x - 4y = 7\\ and\\ 5x + 2y = 3{/tex}Now, {tex}3x - 4y = 7{/tex}{tex}y = \\frac { 3 x - 7 } { 4 }{/tex}When x = 1 then, y = -1When x = -3 then y = -4\tx1-3y-1-4\tNow, 5x + 2y = 3{tex}y = \\frac { 3 - 5 x } { 2 }{/tex}When x = 1 then, y = -1When x = 3 then y = -6Thus, we have the following table\tx13y-1-6\tGraph of the given system of equations areClearly the two lines intersect at A(1, -1)Hence, x = 1 and y = -1 is the solution of the given system of equations. | |
