-x + 4 = -7
(take away 4 from both sides of the equation)
-x = -11
(times both sides by -1)
x = 11
(-11 + 4 = -7)
If: 7+t = 11 Then: t = 11-7 So: t = 4
2x+3 = 7 2x = 7-3 2x = 4 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+4 = 2x-3 3x-2x = -3-4 x = -7
n= -2
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
If: 7+t = 11 Then: t = 11-7 So: t = 4
x=4 y=x+3 y=4+3 y=7
2x+3 = 7 2x = 7-3 2x = 4 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+4 = 2x-3 3x-2x = -3-4 x = -7
n= -2
x=7
7
v = -6
p is obviously zero because any number x plus 0 equals itself.
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
