**HELP!!!!!!!! please!!!!!**

solve the system using substitution {x+2y=11 {3x+2y=13 i just told you how to do the other one; it's the same exact method. solve for x and y. you get: x=-2y+11 and y=(-1/2x)+(11/2). then plug them both back into the original equation (either one, it doesn't matter); ...

**i really, really, really need help**

what coordinate point is the solution to the system? {3x+2y=8 {x-y=1 (2,1) please don't think i just made that up, it's correct. you have to use substitution, when you do solve for x and y, you get: x= y+1 and y=x-1, plug in y for 3x+2y=8 and you get: y=1, then plug in...

what coordinate point is the solution to the system? {3x+2y=8 {x-y=1 y=x-1 so 3x+2(x-1)=8 3x+2x-2=8 5x-2=8 5x=10 - - 5 5 x=2 Then 2-y=1 -2 -2 -y=-1 y=1 Well, to cut the crap the answer is (2,1)

Count Iblis how do you simplify 3square root sign with this underneath (3x squared y) to the third power? "3 square root sign" probably means "cube root", in which case [(3 x^2y)^3]^(1/3) = 3 x^2 y The cube root of any quantity x can be written x^(1/3)

Count Iblis what is the answer to 2 square root sign 18x? The instructions say to simplify or reduce. 2*(18x)1/2= 2*(9*2)1/2= 2*3(2)1/2= 6*(2)1/2 If you can leave it in this form, the above is the way to end. If you are to continue to a final answer, then, finish by 6*1.414 =8...
