Step-by-step explanation:
Answer:
(5,-2)
Step-by-step explanation:
9x+5y=35
2x+5y=0
Multiply the second equation by -1
-1 (2x+5y) = 0*-1
-2x-5y = 0
Add the first equation and the modified second equation
9x+5y=35
-2x-5y = 0
-------------------
7x = 35
Divide by 7
7x/7 = 35/7
x = 5
Now we need to find y
2x+5y = 0
Substituting in x
2(5) +5y = 0
10 +5y = 0
Subtract 10
10-10 +5y = -10
5y = -10
Divide by 5
5y/5 = -10/5
y = -2
(5,-2)
276÷10 is 27.6 and that's the answer just draw that in long division or multiplication you should get 2,760
X squared+y=18
x+y=6. use elimination method.(+y and +y cancels
x squared -x=x
18-6=12
x=12
for y take one of the above equations
x+y=6(replace x with 12
12+y=6(collect the like terms
y=6-12
y=-6
so x=12 and y=-6
