Answer:
x=50
Step-by-step explanation:
67=x+17
67-17=50
x=50
It means the variable y is equal to the negative variable of x.
For the first question it is (3x-5) degrees second question is (x-5)
N+d=47
5n+10d=295
divide 2nd by 5
n+2d=59
we have
n+d=47
n+2d=59
eliminate n
multiply first equaton by -1 and add to other equaton
-n-d=-47
<u>n+2d=59 +</u>
0n+1d=12
d=12
sub back
n+d=47
n+12=47
minus 12 both sides
n=35
