Step-by-step explanation:
(X + y = 26) (-3)
3x + y = 56
____________
- 3 x - 3y = - <u>78</u><u> </u> <u> </u> <u>Note</u>: cross <em>3x</em> and<em>-3x</em> from both equations (they're opposite)
3x +y =56
____________
-3y +y = - 78 +56
-2y = - 22
____________
So we replace y in eq 2: (to obtain x)
3x + 11 =56
3x =45
X =15
Answer:
x = 15
y = 11
Step-by-step explanation:
15+11=26
(3*15)+11=56

The nth term of an arithmetic sequence is found from:
Plugging in the given values, we get for the 13th term:
-58=14+12d
12d =-58 - 14 = -72
d = -6
So, the 32nd term is:
