Equation 1) 3x + 2y - 5z = 3
Equation 2) 4x - 2y - 3z = -10
Equation 3) 5x - 2y - 2z = -11
Add equation 1 with equation 2.
Equation 4) 7x - 8z = 7
Then subtract equation 3 from equation 2.
Equation 5) -x -z = 1
Multiply all of equation 5 with 7.
5) -7x - 7z = 7
4) 7x - 8z = 7
Add equations together.
z = 14
Plug in 14 for z in equation 4.
7x - 8z = 7
7x - 8(14) = 7
7x - 112 = 7
7x = 119
x = 17
Plug in 17 for x in equation 1, and 14 for z.
1) 3x + 2y - 5z = 3
3(17) + 2y - 5(14) = 3
51 + 2y - 70 = 3
2y - 19 = 3
2y = 22
y = 11
So, x = 17, y = 11, and z = 14
~Hope I helped!~

What is the question
Step-by-step explanation:
idk the question so, idk the answer
m = -6
evaluate -m
so -m = -(-6) which would equal 6
Answer is C
Kloe can make 4 flower arrangement
The number of flowers in each flower arrangement is 6 sun flowers, 4 roses and 12 white carnations.
The number of flower arrangements can be calculated as follows;
The first step is to calculate the HCF between the three numbers
24= 6 × 4
16= 4 × 4
48= 12 × 4
The HCF is 4
Hence the number of flower arrangement is 4 and the number of flowers in each flower arrangement is 6 sun flowers, 4 roses and 12 white carnations
