I would plug in each of the solutions to every equation and see which one works. This is probably easier than solving for x, y, and z. But let me know if you would like me to run through the steps!
First choice: using the first equation, -3(-3)-4(4)+6=-19 not -1 as listed. False.
Second choice: using the first equation, -3(4)-4(-3)+(-1)=-1 ; using the second equation, 2(4)+(-3)-(-1)=6 not -8 as listed. False.
Third choice: using the first equation, -3(-3)-4(4)+8=-17 not -1 as listed. False.
Fourth choice: using the first equation, -3(3)-4(-4)+-(-6)=-1 ; using the second equation,
2(3)+(-4)-(-6)=8 ; using the third equation, 3+8(-4)-(-6)=23
So the answer should be the fourth choice. Hope this helps! :)
Answer:
C
Step-by-step explanation:
its also in the lymphatic system.
Answer:
Step-by-step explanation:
Since the two triangles are similar;
This implies that;
Multiply both sides by 18
Answer:
D.
Step-by-step explanation:
12x + 7x = 19x
-7 + +9 = 2
Answer: Subtract 18 on both sides is wrong. Its supposed to be add 18 on both sides.
