Question

solve each system by elimination
6x+8y=-16
7x+16y=-12
and show work please

Answer 1

If you multiply both sides of the first equation by 2 it will be possible to eliminate the y terms by subtraction.
12x + 16y = -32
7x + 16y = -12
Subtracting the second equation from the first we get
5x = -20
Now you can solve for x.

Answer 2

8y=-6x-16
y=-6/8x-6 or 3/4x - 2

7x+16(3/4x - 2)=12
7x+12x-32=12
19x=44
x=44/19

Answer 3

how would you solve for y

Answer 4

And put numbers and explain it good because this part confuses me

Answer 5

The value of x is -4. We can chose either of the original equations an plug in -4 in place of x.
Lets take the first equation, 6x+8y=-16
Putting -4 in place of x we get
\[(6\times -4)+8y=-16\]
which simplifies to
\[-24+8y=-16..............(1)\]
Now can you add 24 to both sides of equation (1) to eliminate the -24 term from the left hand side?

Answer 6

Can you explain to me in numbers please

Answer 7

What does the following equation simplify to?
-24 + 24 + 8y = -16 + 24

Answer 8

I mean explain how to find y in numbers

Answer 9

I have just given the first stage of finding the value of y.
Can you simplify the following equation which has one term in y and the remaining terms are numbers?
-24 + 24 + 8y = -16 + 24

Answer 10

can you go through the steps of the processs to find y totally because I am confused

Answer 11

Sure.
What is the result of the following:
-24 + 24 = ?

Answer 12

-1

Answer 13

am I correct

Answer 14

-24 + 24 = 0
Now can you try the following:
-16 + 24 = ?
