One solution.
-20 divided by 5 is equal to -4. Unless both sides have the same number or one side has -=0 then it’s one solution
We are given with two equations to find the values of two variables, hence the problem can be solved.
Adding the two equations:
x + y = 12<u>x - y = 10
</u>2x = 22
<u />x =11
y = 1
I think y=0 because 6 multiple by 0 is 0 then x= 6 hope this helps might want to check my work to
What you would do is simply plug in 8 where y is and solve.
5(8)=3478-3c -Times 5 by 8
40=3478-3c -Add 3c to the opposite side of the equal sign
40+3c=3478 -Subtract 40 from the opposite side of the equal sign
3c=3438 -Divide equation by 3
c=1146
Hope this helps! :)
