-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
3x - 7 = 2 3x = 9 x = 3
x+7=3x+3 4=2x 4/2=2 x=2
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
3x + 7 = 6x - 2 Rearranging gives 6x - 3x = 7 + 2 3x = 9 x = 3
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
3x - 7 = 2 3x = 9 x = 3
x+7=3x+3 4=2x 4/2=2 x=2
If 7 > 3x - 2 then x < 3.
3x - 2 = 19Add 2 to each side:3x = 21Divide each side by 3:x = 7
3x + 7 = 3(-3) + 7= -9 + 7= -2
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
eq: 3x+5=7 =3x=7-5 =3x=2 =x=2/3
Since x = -3, then 3x = -9 therefore; -9 + 7 = -2 _____________________________________________________________________ 3x+7=-3 so -3-7=-10 so 3x has to equal -10. so 3 x -3.333...=-10 Answer: -3.3333....
3x + 7 = 6x - 2 Rearranging gives 6x - 3x = 7 + 2 3x = 9 x = 3
x^2 + 3x + 3 = 7 x^2 + 3x - 4 = 0 (x - 1)(x + 4) = 0 x = 1 or x = -4
