Answer:

x=20; y=50 or (20, 50)

Step-by-step explanation:

Substitution means plugging in one variable's value that consists of the opposite variable. Because y=3x-10 is already specified, you can plug it into the second equation's y value. After doing that, it looks like this:

-4x+2y=20→-4x+2(3x-10)=20

Then you would distribute the 3 across the parentheses next to it, like this:

-4x+2(3x-10)=20→-4x+6x-20=20

Then, add like terms, like this:

-4x+6x-20=20→2x=40

Then divide both side by 2 to isolate x.

x=20

Now, you can plug 20 (x) into either equation, but the first one seems simpler so you would pick that. It would look like this:

y=3x-10→y=3(20)-10

Solving would look like this:

y=3(20)-10→y=60-10→y=50

So the answer is x=20; y=50 or (20, 50).

bazaltina [42]

Answer:

145/2

Step-by-step explanation:

d=[2x+1-x] = [5x+1 -(2x+1)]

x+1=3x

x-3x=-1

-2x=-1

x=1/2

therefore first term is 1/2

second term is 2(1/2)+1= 2

common difference d is 2-1/2=3/2

sum of first n terms is n/2 [2a+(n-1)d] where n=10

sum of first 10 terms= 10/2[2×1/2+(10-1)3/2]

=5[1+(9)3/2] =5[1+27/2] = 5[29/2] =145/2
