Question

4
+
3
+ 3y = 14,
X
- 4y = 23,
solve for x and y by reducing them to a pair of linear​

Answer 1

Step-by-step explanation:

4+3+3y = 14

7+3y = 14

3y = 14 -7

3y = 7

y =7/3

substitute y = 7/3 in other eqn

x-4y = 23

x- 4×7/3= 23

x- 28/3=23

x - 28 = 23 ×3

x - 28 = 69

x= 69+28

x = 97
