The equation can be solved by isolating the variables from the numbers. The answer would be 4x = 8, which equals 2.
3x + (-2 + 4x) = -2 + 7x
x2+7x=-2x2+6 3x2+7x-6=0 (3x-2)(x+3)=0 3x-2=0 or x+3=0 x=2/3 or x=-3
(x + 1)(3x + 10)
The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth
-7x + 6 + 7x - 2 = 4
simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
3x + (-2 + 4x) = -2 + 7x
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
(3x+2)-(5+7x) = 3x+2-5-7x = -4x-3 3x+2 is -4x-3 times greater than 5+7x.
You're asking for the difference: (3x + 2) - (5 - 7x).(3x + 2) - (5 - 7x) =3x + 2 - 5 + 7x =10x - 3.It is (10x - 3) greater.
3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
Answer : 12
7x + 5 + 3x is [ 10x + 5 ].That's the same thing as [ 2 times (5x + 1) ] .
7x+8
It is a quadratic expression and can be factored into: (3x+1)(x+2)
7x - 2 = 4x + 9 3x - 2 = 9 3x = 11 x = 11/3
