X+Y=14 and X-y =4 |
| Answer» Given=> x + y = 14. .... equation 1x - y = 4. ...... equation 2Now, we will solve it by substitution method;Let\'s take equation 1 =>x + y = 14x = 14 - yPut the value of x in equation 2=>x - y = 4=> 14 - y - y = 4=> 2y = 14 - 4=> y = 10/2=> y = 5Now, put the value of y in equation 1 =>x + y = 14=> x + 5 = 14=> x = 9Therefore the value of x = 9 and y = 5 | |
