- 8x+5y=9 3x+2y=4
- p=2q-1,q=5-3p
- 2x+3y=31 5x-4=3y

7X+8=10
- 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
- 2x-3y=7,5x+y=9
- the sum two number x and y is 10 and their product is 8.
- 23x+31y=77,31x+23y=85
- 3x-y=23 x/3+y/4=4
