3x + 4 = -2
3x = - 2 - 2
x = -4/3
* * *
See if this doesn't work better:
3x = -2 - 4 = -6
x = -2
Check:
Substitute -2 for x, in the original equation.
3(-2) + 4 = -6 + 4 = -2; thus, the answer is shown to be correct.
-3x+2 = -4
-3x = -4-2
-3x = -6
x = 2
(2, -1)
Their graphs are.
(-2, 4)
3x = -12 so x = -4
2x-4
3x + 2 = -10 3x = -12 x = -4
x = 7 and 2/3
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
x=2
x = 4
x+7=3x+3 4=2x 4/2=2 x=2
