What is x-2y=-1 and 2x+y=4 using elimination step by step
otez555 [7]

Answer:

x = 7/5  , y = 6/5

Step-by-step explanation using elimination:

Solve the following system:

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

2 x + y = 4 | (equation 2)

Swap equation 1 with equation 2:

{2 x + y = 4 | (equation 1)

x - 2 y = -1 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + y = 4 | (equation 1)

0 x - (5 y)/2 = -3 | (equation 2)

Multiply equation 2 by -2:

{2 x + y = 4 | (equation 1)

0 x+5 y = 6 | (equation 2)

Divide equation 2 by 5:

{2 x + y = 4 | (equation 1)

0 x+y = 6/5 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 14/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 7/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Collect results:

Answer: {x = 7/5  , y = 6/5

Kayla ran from her home to a beach at a speed of 6 meters per second. the distance from her home and the beach was 756 meters. A
german
Looking at the units, 756 meters divided by 6 m/s will give you the seconds that you need.

So for A) 756/6 = 126

For B, you take the answer from A, and subtract 18 seconds, which would make it 108.  Then you take the distance, 756 and divide by 108, that will be the speed.
