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...
PLEASE!!!!i need help on these 4:*4y=15-3x2y=3x+21*4x=5y-14y=-6x-9*5x=4y-302x=3y=-12*2/3y=10+4x5x=1/3y-8use linear combinations to solve the system of linear equationsthank you!!!
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
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
