x=7 3/4
42?
x/2 = 21 x = 42
x equals 25
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
x=7 3/4
If 40 plus x equals 25 then x is equal to -15.
42?
x/2 = 21 x = 42
x equals 25
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
x=4 y=0
4x+9=25 4x=16 x=4
(20 x 4) + 25 - 52 = 53
If you mean: 2x+5+3x = 25 then the value of x works out as 4
4x + 5 + x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
4x + 9 = 254x = 25 - 94 x = 16x= 16/4x= 4
