Z - 12 = 6<br> A. 10<br> B. 15<br> C. 18<br> D. 6<br><br> Need help working it out
const2013 [10]
Z-12=6

you take the 12 and add it to both sides making it look like:
z-12+12=6+12
which also looks like
z-0=6+12

z-0 = z

so now you have
z=6+12

6+12 = 18

SO Z=18!!!

your answer is 18

If x=2k + 1, y=k - 1 is a solution of the equation 2x - 3y + 5=0. find the value of k.​
devlian [24]

Answer:

x = 2k + 1 \\ y = k - 1 \\ given

if u substitute the givens in the eqn we will get..

2(2k + 1) - 2(k - 1) + 5 = 0 \\ 4k + 2 - (2k - 2) + 5 = 0 \\ 4k + 2 - 2k + 2 + 5 = 0 \\

then collect like terms

4k - 2k + 2 + 2 + 5 = 0 \\ 2k + 4 + 5 = 0 \\ 2k + 9 = 0

2k =  - 9 \\ k =  \frac{ - 9}{2}

11x+4y=-46<br> 7x-4y=10 <br> Find x and y
UNO [17]

Answer:x=-2 y=-6

Step-by-step explanation:

11x+4y=-46..........(1)

7x-4y=10..............(11)

Add (1) and (11)

11x+7x+4y-4y=-46+10

18x=-36

Divide both sides by 18

18x/18=-36/18

x=-2

substitute x=-2 in (11)

7x-4y=10

7(-2)-4y=10

-14-4y=10

Collect like terms

4y=-14-10

4y=-24

Divide both sides by 4

4y/4=-24/4

y=-6
