X plus y equals 7 and x plus 2y equals 11?
x=3 and y=4. you multiply x+y=7 by neg. 2 this way you can cancel out the y factors and get neg. 2x+x=-14+11 neg. x = neg. 3 divide both sides by neg. 1 to get x=3. use substitution to get y=4
What two integers have a product of -24 and a sum of 2?
6 and -4, because a neg. times a pos. equals a neg. (in this case 6*(-4)= -24) and when adding and subtracting integers you subtract the smaller number from the larger number, in the case 6 and 4, which is 2
