substitute the value of x which is 3 :10/ (2-x)+4 = -10+4= -6
this works out as 37 - (5/2) + (4 x 3) = 37 - 2.5 + 12 = 46.5
-4
6x + 9 = -3 6x/3 + 9/3 = -3/3 2x + 3 = -1 2x + 3 - 3 = -1 - 3 2x = -4 2x/2 = -4/2 x = -2
-5
If you mean: 4(2x-2) = 4-4(x-3) then the value of x works out as 2
x can have any value in the domain.
-3x - 2 = -6 -3x = -6 + 2 -3x = -4 -x = -4/3 x = 4/3 The absolute value is therefore 4/3.
x-2 and x -7?
Y = X+3, therefore: 3 1/2 4 1/2 5 1/2 7 1/4 7 3/4
If you mean: 3(x+5) = 4(x-2) then the value of x works out as 23
3
substitute the value of x which is 3 :10/ (2-x)+4 = -10+4= -6
Well if 3x-1 = 11 then 3x = 12 12/3=4 x=4 x^2+x=4^2+4 4^2+4 = 20 Hope this is of help to you. :]
3xy = 3 times 5 x 2 = 30 4y cubed = 4 times 2 x 2 x 2 =32 Total value 62

Assume that the expression 4x5 in the question is 4x5.4x5 = 3 : x5 = 3/4 : x = 5√(3/4) : then 2k.5√(3/4) + 10 = 2 : 2k.5√(3/4) = 2 - 10 = -8 :k = -4 ÷ 5√(3/4) = -4 ÷ 0.9441 = -4.2369 (4dp)
