8x = 5x+24 8x-5x = 24 3x = 24 x = 8
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
To simplify the expression 5x - (-3x), you can rewrite it as 5x + 3x since subtracting a negative is the same as adding a positive. This simplifies to 8x. So, the result of 5x - (-3x) is 8x.
5x+8x+3x-2x = 14x
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
x/3=x/8-10/1 find the common denominator which is 24 8x/24=3x/24-240/24 put the numirator in a equation 8x=3x-240 do 8x-5x 5x=-240 divide it by 5 x=-48
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4
