Answer: x= -4/3

Step-by-step explanation:

1) Ok first you want to distribute 2 with 2x and 10x , so multiply 2 with 2x and 10x

You would get -32= 4x+20x

2) then you add the x together which is -32= 24x

3) your goal is to get x by itself,what u would do is divide 24 on both sides and you are left with -32/24= x

4) be careful you are not done yet because you have to simplify-32/24, if you simply it, you would get -4/3 because -32 and 24 is divisible by 8.

So your answer would be x = -4/3

-19 to -15 would be a positive 4 difference

19 to 15 = 4 this would be a -4 difference

3 to 7 is a positive 4 difference

-3 to 7 is a difference of 10

so there is 1 with a -4 difference
answer is B.

Solve the system by using the technique of ‘elimination’: -2x+5y=-42,7x+2y=30

Gekata [30.6K]

Solve the following system using elimination:

{5 y - 2 x = -42 | (equation 1)

7 x + 2 y = 30 | (equation 2)

Swap equation 1 with equation 2:

{7 x + 2 y = 30 | (equation 1)

-(2 x) + 5 y = -42 | (equation 2)

Add 2/7 × (equation 1) to equation 2:

{7 x + 2 y = 30 | (equation 1)

0 x+(39 y)/7 = (-234)/7 | (equation 2)

Multiply equation 2 by 7/39:

{7 x + 2 y = 30 | (equation 1)

0 x+y = -6 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{7 x+0 y = 42 | (equation 1)

0 x+y = -6 | (equation 2)

Divide equation 1 by 7:

{x+0 y = 6 | (equation 1)

0 x+y = -6 | (equation 2)

Collect results:

Answer: {x = 6, y = -6
