Which could be the first step in solving this system of equations by substitution?
Ainat [17]

Answer:

The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)

solve and get

(2.5,17.5)

or x= 2.5 y=17.5

Step-by-step explanation:

The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x

7x-x=15

6x=15

x=2.5

Then we can solve for y

y=7(2.5)

y=17.5

I need x+y=5 and y=2x-4solved algebraically
schepotkina [342]

Answer:

x = 3; y = 2

Step-by-step explanation:

x + y = 5

y = 2x - 4

<em>Isolate the y in the first equation</em>

y = 5 - x

y = 2x - 4

<em>Substitute the values</em>

5 - x = 2x - 4

<em>Isolate the Variable</em>

9 = 3x

<em>Simplify</em>

3 = x

<em>Plug that into the first equation</em>

3 + y = 5

<em>Subtract 3 from both sides</em>

y = 2
