For what value of c, the linear equation 2x + cy = 8 has equal values of x and y for its solution. Given: y = x is a solution to the equation 2x + cy = 8 Put x = y We have: 2y + cy = 8 Or, cy = 8 − 2y c = `8/y - 2 = 8/x - 2` Concept: Solution of a Linear Equation Is there an error in this question or solution? |
