6x - 14 = 3x + 5Subtract 3x from each side: 3x - 14 = 5Add 14 to each side: 3x = 19Divide each side by 3: x = 19/3
15 + 14 + 14 + 11 + 2x + x = 75 Collect like terms 54 + 3x = 75 Subtract 54 3x = 21 Divide by 3 x = 7 ■
3x+7=4x 7=4x-3x 7=x
The slope equals 3
3x+5y=48 5y=48-3x-3x+5y=12 -3x+(48-3x)=12-6x=-36x=65y=48-3(6)5y=30y=6(6,6)
3x + 5 = 6x + 23 -3x = 18 x = -6
-3x+14 = -4 -3x = -4-14 -3x = -18 x = 6
8x - 23= 3x + 2 +23 +23 8x=3x + 25 -3x -3x 5x=25 x=5 the answer is X=5
3x+5=14 3x=9 x=3
undefined.
If: 3x+7 = -14 Then: x = -7
(4, 5)
3x+50=6x+14 50-14=6x-3x 36=3x x=36 / 3 therefore x=12
x = 4
23
3x - 12 = -2x + 235x = 35 so x = 7
If: 3x+8 = 14 Then: 3x = 14-8 So: 3x = 6 Divide both sides by 3: x = 2
