Question 177756
Y  =  6  -  3x 
Y  =  2x  +  1
Substitute the y-value in eq (i) into eq (ii). This gives us:
6   -   3x   =   2x   +   1
- 5x   =   - 5
x   =   1

Substitute this x-value in eq (ii), we get: y  =  2(1) + 1
Y  =  3

Answer – (1, 3)

You should now be able to do the next one. Good luck!!
