9.8 / 1, but fractions don't like decimals, so 98/10
90/10 is 9, so 9 with 8/10 remaining.
8/10 can be simplified to
4/5
So it is 9 and 4/5
We can solve this by elimination, in order to do this we need to multiply the bottom equation by three to cross out the X
(x+5y=38)3 3x+15y=114
-3x+4y=95
3x+15y=114
then add the two equations together and the X will cancel out
19y=209
----- -----
19 19
y=11
then plug that in into one of the equations
x+55=38
-55 -55
x= -17
your answer is (-17,11)
Answer:
6x^2−3x
Step-by-step explanation:
so first you have to multiply the 3x to both 2x and 1
the equation is now 6x^2-3x
there are no more like terms so the answer is 6x^2-3x
