- Solve the following simultaneous equations by substitution method: 8 y = 11 ; 3 – y = 2
- solve 2x + = 35 , 3x + 4y = 65 hence find the value of x/ y
- the sum two number x and y is 10 and their product is 8.
- 3x-y=23 x/3+y/4=4
- x +2y = 1 , 3x - y = 17 by substituting method
- 4/x-9/y=5 7/x-12/y=20 I did not understood how to solve this
