Answer:
2x+11+11+x+3+3x-2=59
6x+23=59
6x=36
x=6
3x-2=18-2=16
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
2 x 6 = 12
12 - 4 = 8
So, our answer is 8.
Y *x =20
y +x =9
rewrite 1st eq. as y = 20/x
subsituute that into 2nd eq.
20/x +x =9
multiply each term by X
20 +x^2 = 9x
subtract 9x from each side:
x^2 - 9x +20 = 0
now factor:
(x-5) (x-4) = 0
solve for x
5-5 = 0
4-4 = 0
so X can be 4 or 5
replace x into equations and solve for Y
so when X = 4, Y = 5
When X = 5, Y = 4
x= 5,4
y = 4,5
Answer:
