2x + 3y = 29x= 4
find x
29x= 4
x = (4/29)
sub x into the first part of the sum
2x + 3y = 4
2*(4/29) + 3y = 4 note * means multiply
(8/29) + 3y = 4
3y = 4 - (8/29)
3y = (108/29) note 4* 29 minus 8 = 108
y = (36/29)
there is probably a quicker way to do this.

2x+32 = 1 2x = 1-32 2x = -31 x = -15.5
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
2x+8 = 6 2x = 6-8 2x = -2 x = -1
2y = 4x + 4y = 2x + 2
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
