-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
If: 3x-7+x = 5 Then: x = 3
3x+5 = 26 Subtract 5 from both sides: 3x = 21 Divide both sides by 3 to find the value of x: x = 7
3x - 6 + 1 = 7Combine the -6 and the +1 on the left side of the equation :3x - 5 = 7Add 5 to each side:3x = 12Divide each side by 3 :x = 4
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3X - 7 = 5 add 7 to each side 3X - 7 + 7 = 5 + 7 3X = 12 divide both sides constants and coefficients by 3 X = 4 check 3(4) - 7 = 5 12 - 7 = 5 5 = 5 checks
3x + 7 = 22 Subtract '7' from both sides Hence 3x = 15 Divide both sides by '3' x = 5 The answer !!!
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
eq: 3x+5=7 =3x=7-5 =3x=2 =x=2/3
7/3
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
If: 3x-7+x = 5 Then: x = 3
3x+5 = 26 Subtract 5 from both sides: 3x = 21 Divide both sides by 3 to find the value of x: x = 7
6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)
It depends on the value of x. -3 = 4 -3x 3x = 7 so x =7/3 If x < 7/3 then -3 is greater if x = 7/3 then -3 is the same if x > 7/3 then -3 is smaller.
5 - 3(-7) = 26.
