Solution:
The given equation is:
A: Taking , x=1
L H S = 9 × 1 + 49 = 9 + 49= 58
R H S : 
L H S ≠ R H S
B: Taking x=3
L H S = 9 × 3 + 49=27 + 49=76
R HS = 
L H S ≠ R H S
C: Taking x=5
L H S = 9 × 5 + 49
= 45 + 49
= 94
R H S:
L H S ≠ R H S
(D)
when , x= 8
L H S
9 × 8 + 49
= 72 + 49
= 121
R HS:
L H S ≠ R H S
Answer:
the answer is the last one
Step-by-step explanation:
Answer:
The result is that you eliminate the 7y term and thus can solve for x.
x = -28/3
y = 30/7
Step-by-step explanation:
-20 + 7y = 10
3x + 7y = 2
subtract... elimination method
-20 - 3x = 8
-3x = 28
x = -28/3
-20 + 7y = 10
7y = 30
y = 30/7
