If you mean 8 time 3, then 24. If you mean 8x + 3, where x is a variable, then no value can be determined until the value of the variable, x, is known. (Same for 8x - 3) If you mean 8x3 , once again is unknown but the value of x would be multiplies as a factor 3 times. what about 8x = 3, then there is an algebraic answer. x = 8/3 or 2 2/3 So you need to make your question more mathematically correct so it can be answered.
0.5*8=.40
If you mean -3(x+5) = 8x+18 then -3x-15 = 8x+18 and the value of x works out as -3
- 8x + 8x = 0 so question is meaningless.
If: 8x+12x = 90 Then: 20x = 90 And: x = 4.5
18.4
you times that number by the one replaced with x

-119 - 7x = 8x + 16Add 7x to each side of the equation:-119 = 15x + 16Subtract 16 from each side:-135 = 15xDivide each side by 15:-9 = x
8x / 15 = 80Multiply each side by 15:8x = 1,200Divide each side by 8:x = 150
- 8x + 8x = 0 so question is meaningless.
If you mean: 8x = 120 then the value of x is 15
-8x = 32Divide each side by 8:-x = 4Multiply each side by -1:x = -4
You don't solve this. It is an identity. 8X - 14 = 8X - 14 add 14 to each side 8X = 8X divide both sides integers by 8 X = X =============X can be any number you want.
Choose any value for x. Calculate 8x to get the corresponding value for y.
