5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
3x + 4 = 16 3x = 16 - 4 x = 12/3 x = 4
7x + 16 = 3x + 4 4x = -12 x = -3
x = 7 and 2/3
If: 3x+5 = 4x+1 Then: x = 4
x = 4
x = 6
x = 3 and 1/3
9x + 2 = 12x + 14 -3x = 12 x = -4
(2, -1)
Their graphs are.
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
3x+10=14+2x so subtract 2x from both sides x+10=14 so x=14-10 so x = 4
3x+56 = 2x+4 3x-2x = 4-56 x = -52
x=6
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
3x+8 = 12 3x = 4 x = 4/3
