The answer would be: x+2y

First, combine the like terms.

-x and 2x

Now your equation looks like this:

x+y+y

Now combine the y like terms.

y and y and you get 2y

Then you are left with your answer: x+2y

Hope this helps! :3

Answer:

x + 2y

Step-by-step explanation:

Firstly, you collect like terms:

Write an equation of the line through (6,-5) having slope 0. Give the answer in standard form.
allsm [11]

0x + 1y = -5 is the standard form of equation

<em><u>Solution:</u></em>

Given that we have to write the equation of line passing thorugh (6, -5) and has slope 0

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ---------- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that, m = 0

Given point is (6, -5)

<em><u>To find the y - intercept:</u></em>

<em><u>Substitute (x, y) = (6, -5) and m = 0 in eqn 1</u></em>

-5 = 0(6) + c

c = -5

<em><u>Substitute c = -5 and m = 0 in eqn 1</u></em>

y = 0x + (-5)

y = -5

<em><u>The standard form of equation is given as:</u></em>

The standard form of an equation is Ax + By = C

In this kind of equation, x and y are variables and A, B, and C are integers

y = -5

0x + 1y = -5 is the standard form of equation

Solving systems of equations using any method
andreev551 [17]

Answer:

x = 5 , y = 2

Step-by-step explanation:

Solve the following system:

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

{y = (3 x)/5 - 1 | (equation 2)

Express the system in standard form:

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

{-(3 x)/5 + y = -1 | (equation 2)

Subtract 3/7 × (equation 1) from equation 2:

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

{0 x+(4 y)/7 = 8/7 | (equation 2)

Multiply equation 1 by 5:

{-(7 x) + 5 y = -25 | (equation 1)

{0 x+(4 y)/7 = 8/7 | (equation 2)

Multiply equation 2 by 7/4:

{-(7 x) + 5 y = -25 | (equation 1)

{0 x+y = 2 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{-(7 x)+0 y = -35 | (equation 1)

{0 x+y = 2 | (equation 2)

Divide equation 1 by -7:

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

{0 x+y = 2 | (equation 2)

Collect results:

Answer:  {x = 5 , y = 2
