4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
many solutions
2y + 4 = 3ySubtract 2y from both sides:4 = ywhew
3x+2y=6 2y=-3x+6 y=-1.5x+3
Subtract by 7x and divide by 2.
2y = 4x + 4y = 2x + 2
you can not solve this equation

3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
3x+2y=6 2y=-3x+6 y=-1.5x+3
Subtract by 7x and divide by 2.
6x+2y=4 gives y=2-(1/3)x
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
