The mistake is that the multiplication operator takes precedence over the addition operator, meaning you first have to perform the multiplication of the two numbers before you perform the addition of the two numbers.
So, instead of doing: 8 x (4+4) = 8 x 8 = 64
You should do: (8 x 4) + 4 = 32 + 4 = 36
Y-8x plus 9y equals 10y-8x.
8x-7 plus 2x equals 6 plus 5x plus 2?
-8x - 10 - 20 = -8x - 30
8x + -2 = 10 8x = 12 x = 1.5
2x^2 + 8x + 3 = 0
-8x + 6 = -58 -8x = -64 x= -64/-8 x = 8
basic algebra -8x + 6 = -58 -8x = -64 x = (-64/-8) x = 8
This can't be solved. You have two varibles.
-8x-8y=-64 -8y=8x-64 y=-x+8
Y-8x plus 9y equals 10y-8x.

3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
8x plus 4y equals 5 is 8x + 4y = 5.
No.
- 8x + 8x = 0 so question is meaningless.
8x-7 plus 2x equals 6 plus 5x plus 2?
