Multiply the first equation by -2 to give 

4x - 2y = 6
-x + 2y = 3     Adding:-
3x = 9
x = 3
Plug x = 3 into second equation:-
-3 + 2y = 3
2y = 6
y = 3


Answer is x=3, y = 3

How many solutions are there to 3x-10(x+2) =13-7x
Vaselesa [24]

This is the following way to solve this problem:

3x-10(x+2)=13-7x

3x-10x-20=13-7x        (multiply 10 times what's in the parentheses)

-7x-20=13-7x              ( subtract 3x from -10x)

-7x-20-13=-7x             ( since the 13 is positive, when we move it to the other

                                   side, we change it's sign, so now we subtract 13 from 20

-7x-7=-7x

-7=-7x+7x                   ( we do the same thing we did above, now with the -7x)

-7=x

x=-7

Answer: x = -7

Will give brainliest and 5stars and thank you if youre answer is right
slega [8]

Step-by-step explanation:

since

25⁰= 1 minute

x⁰ = 11 minutes

cross multiply

25 x 11= x

x= 275⁰

temperature after being turned on=275⁰

temperature after 11 minutes= 275⁰ + 75⁰= 350⁰

temperature(x) after being turned on

25tt=x

temperature (x) after minutes

x= 25tt + 75⁰
