sept. 18

we looked at intense coeficents.and changed them to our liking.

sept. 17

2x+4y=8
3x+y=-13

first. find the 1 coeficent. thats in the 2nd equation. then i subtracted 3x. then i substituted (-13-3x) for y in the 1st equation. i then had 2x+4(-13-3x)=8. i evaluated that to 2x-52-12x=8. after collectiong like terms, getting rid of -52, i had -10x/-10 = 60/10. therefor, x= -6. after i figured out x, i substiued that into the first equations and then it was just algebra to find out what y was. y= 5
