So d is the correct answer
Total heads = 10
Total legs = 26
Cat = 4 legs
Birds = 2 legs
------------------------------------
Assumed all birds :
------------------------------------
Total legs = 10 x 2 = 20
------------------------------------
Difference in legs :
------------------------------------
26 - 20 = 6
------------------------------------
Difference in legs between the two animals:
------------------------------------
4 - 2 = 2
------------------------------------
Find number of cats :
------------------------------------
6 ÷ 2 = 3
------------------------------------
Find number of birds :
------------------------------------
10 - 3 = 7
------------------------------------------------------------------------
Answer: There are 3 cats and 7 birds.

Answer: x = -3, y = 2
<u>Step-by-step explanation:</u>
3x + 2y = -5 → 3(3x + 2y = -5) → 9x + 6y = -15
4x - 3y = -18 → 2(4x - 3y = -18) → <u> 8x - 6y </u>= <u>-36 </u>
17x = -51
<u> ÷17 </u> <u>÷17 </u>
x = -3
3x + 2y = -5
3(-3) + 2y = -5
-9 + 2y = -5
<u> +9 </u> <u> +9 </u>
2y = 4
<u> ÷2 </u> <u>÷2 </u>
y = 2
