Solving simultaneous equations using elimination

Need help solving these, please give as much working out as possible because I don't know what to do :D helps me out alot! 11 points
1. Solve by adding equations to eliminate either x or y.
b. 5x + 4y = 2 // c. −2x + y = 10
5x − 4y = −22 // 2x + 3y = 14
2. Solve by subtracting equations to eliminate either x or y.
a 3x + 2y = 13 // b. 2x − 5y = −11 //c. −3x − y = 8
5x + 2y = 23 // 2x + y = 7 // −3x + 4y = 13
3. Solve each of the following equations using the elimination method.
a. x + 2y = 12 //b. 3x + 2y = −23 //c. 6x + 5y = −13
3x − 2y = 12 // 5x + 2y = −29 // −2x + 5y = −29

1. Solve by adding equations to eliminate either x or y.
Dammit all, you've been *told* what to do.
5x + 4y = 2
5x − 4y = −22
Here, subtract the second equation from the first.
The x term disappears.
8*y = 24
y = 3<<
Substitute,
5*x + 4*3 = 2
5*x = -10
x = -2<<

1c Add eqns.
2a,b,c Subtract eqns
3a add eqns
3b,c subtract eqns.

The way you have typed things makes it impossible to figure out what the problem is supposed to be. You only need to type one set of equations because they are all done the same way.
