3x + 2 = -10 3x = -12 x = -4
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
x = 2
X = -2(13 + y) / 3x = 5y / 4 - 1
4=3x-14 18=3x I carried the 14 over and it became positive. x=6 I divided 18 by 3.
Divide 2 and 4 by 2. The two turns into a 1, and the equation would then look like: 3x=1/2. x=.166666666667
x equals 4 over 35
3x + 4y - 4 = 0 y = -2 3x + 4(-2) - 4 = 0 3x - 8 - 4 = 0 3x = 12 x = 4 (4,-2)
3x + 2 = -10 3x = -12 x = -4
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
-3x -4=2 add four to both sides -3x=6 divide by (-)3 on both sides x= -2 to check: -2(-3) -4=2 6-4=2 It checks.
(2, -1)
Their graphs are.
When x=4, 3x-2 = 3(4)-2 = 12-2 = 10
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
3x = -12 so x = -4
12 + 3x = 412 - 12 + 3x = 4 - 123x = -83x/3 = -8/3x = -8/3x = -(2 2/3)
