The expression 5x - 4 2x - 8 is not written correctly, as there is no operation between the terms 5x - 4 and 2x - 8. It seems like there might be a missing operator, such as a plus or minus sign, between the two terms. Without knowing the intended operation, it is not possible to simplify or evaluate the expression accurately.
2xx-5x-12 2*-12=-24 -24=-8*3 -8+3=-5 2xx-8x+3x-12 2x(x-4)+3(x-4) (2x+3)(x-4)
2x - 4 = 12Add 4 to each side:2x = 16Divide each side by 2:x = 8
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
6x - 8 + 2x - 5 = 7 - 2x ?
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
If you mean: y = -8 and y = -2x-12 then the solution is x = -2 and y = -8
2x - 3 - 8 = 1. 2x - 11 = 1. 2x = 12.x = 6!
2x - 4 = 82x = 8 + 4 = 12x = 12/2 = 6
-4x - 8 = -2x + 12Add 4x to each side:-8 = 2x + 12Subtract 12 from each side:-20 = 2xDivide each side by 2:-10 = x
4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
2x + 8 = 3x - 4 Subtract 2x from both sides: 8 = x - 4 Add 4 to both sides: 12 = x
(2x + 8)/4 = (2x - 8)/3 Multiply both sides by 12 to get rid of the fractions: 3*(2x + 8) = 4*(2x - 8) Simplify: 6x + 24 = 8x - 32 Subtract 6x from both sides: 24 = 2x - 32 Add 32 to both sides: 56 = 2x or 2x = 56 Divide both sides by 2: x = 28
2x + 4y = 12 ie 4y = 12 - 2x so y = 3 - x/2 Test: take x as 8 so y = -1: 2 x 8 + 4 x -1 does indeed = 12.
8 - 2x = -16 Multiply every term by -1 or, equivalently, change the sign of every term. -8 + 2x = 16 Add 8 to both sides: 2x = 24 Divide both sides by 2: x = 12
