solve for X ?1) 8-3x < 14-3x/-3 < 6/-3x=-22) 7x -3 > 4x +3 3x -3> 33x/3 >6/3 x>23) x-5<3 and 2x > -8 x<8 x>-44) x+ 7 <3 or 5x > 30 x<-4 x> 6are they correct..
1. 2x-y=1 6x-3y=3 2. y=5x-1 y=5x+4 3. x+y=38 x=2y-25 4. -2x+5y=9 x+y=13 5. 2x+y=7 3x-y=3 6. y=3x+2 2x+y=-8 7.y=-x-3 y=-2x-8 8. yx+1 9. y=x y=2x-4 10. -2x+y=6 y=3x+9 11. y

I was told to wolve and check the following. {and} represent absolute value. 1) {5x}=302) {-9x}=363) {x-4}=94){x+5}=125){4y-5}=156){5y+3}=97) 3{x+5}=128) 2{3w-2}=149) {2x-3}=-110) {2x-3}=4x-111) {y-5}-2=1012) {3x-1}+10=2513) -{2w-6}=1014) 8{4-3y}=4815) 6{2x+5}=6x+2416) 7{8-3x}=21x-4917) 1/4{4x+7}=8x+16
for #1-7 please solve each of these systems by substitution. show work. please help me.. thanks who ever has the time.. 1). -2x+y=-1 x+y=5 3). 2x+3y=4 x+4y=5 5). 3x-y=2 -2x+5y=6 7). 2x+y=7 -5x-2y=8 these are the next set. solve each system by linear combination. show work please. 9). 3x-2y=4 x+2y=8 11). 2x+y=7 4x+2y=5 13). -3x+2y=4 6x-4y=-8 15). 2x=3y+7 4x+7y=6 remember there are 2 different sets of these systems to be solved.. again please show work so i can understand what...
so i need help with factoring polynomials!! please!! this is urgent! :( 2X^2+3X+1d^2+8d+72a^2+5a+33x^2-x-42n^2+n-6x^2+5x-145x^2-2x-77n^2+9n+23x^2+8x+47a^2-30a+8
1. 3x – 12 = 11 2. 2 – 3(2x + 4) – 8 = 73. 3x – 8 + 6x + 9 = 14 4. 8x – 12 = 5x – 195. 5(2x + 3) – 2x = 4x + 1 6. 3x – 7(x – 8) – 2 = 4x7. 2x + 4(x + 2) – 3 = 7 – x 8. x + 9 – (3x + 1) = 15 – 8x
6. Add: 3/y + y/37. Subtract: x^2/x-2 - 4x-4/x-28. Subtract: 4/a - 12/ a^2+3a9. Simplify: 1/x+1/y/1/x-1/y10. Solve for a: a+4/a^2+5a = -2/a^2-2511. Solve for x: 1 -8/x = -15/x^2
