solve for x show all work these are the problem i can't do
1. (x/a)=b+x
2. x^2+10x=-24
3. c(x+2)+ax=4
i also need help on this problem (x^3-4x)/(x^3-4x^2+4x)
1. (x/a)=b+x, multiply everything by a
x=ab+ax, subtract ax from both sides
x-ax=ab, factor out an x on the LHS
x(1-a)=ab, divide by (1-a)
x=ab/(1-a)
2.x^2+10x=-24, set equal to zero by addding 24 to each side
x^2+10x+24=0, factor
(x+4)(x+6)=0
x=-4 or x=-6
3.c(x+2)+ax=4, distribute the c
cx+2c+ax=4, subtract 2c from each side
cx+ax=4-2c, factor out an x from the LHS
x(c+a)=4-2c, divide by (c+a)
x=(4-2c)/(c+a)
1. im not sure
2. x^2 + 10x +24 = 0
(x+6)(x+4)
x = -6, x = -4
3.cx + 2c + ax =4
cx + ax = 4-2c
x(c+a)=4 -2c
x = (4 -2c)/(c+a)
2) add 24 to both sides . factor . (x+6)(x+4) x=-4, -6
