(-1) 6x + 7y = 3
(6) x + y = 1

-6x - 7y = -3
6x + 6y = 6

-1y = -3

divide both by -1

y = 3


then


6x + 7(3) = 3
6x + 21 = 3
6x = -18

divide both by 6

which equals x = -3

How do you simplify 3(j-2k)+4 ?​
masha68 [24]

Answer: 3j-6k+4

Step-by-step explanation:

First you have to distribute the 3 to the j and the -2k since they are both in the parentheses. So it would look like (3*j) +(-2k*3)+4 and if you simplify that it is 3j-2k+4. After that there are no like terms so that is your answer.

Answer:

x=6,-4

Step-by-step explanation:

Ok so we know the 2 angles are congruent so you need to set them equal to each other. x^2+5x=7x+24. Then get the x's together so you subtract by 7x to get x^2-2x=24. You would then get 24 on the other side so subtract by 24 to get x^2-2x-24. You then would need to factor the equation out. The factored form would be (x-6)(x+4). Then set it equal to 0 to get 6 and -4.

Suzanne bought 50 apples at the apple orchard. She bought 4 times as many red apples as green apples. How many more red apples t
Natali [406]
Let x = the number of green apples, let 4x = the number of red apples
4x + x = 50         Set up the quation
5x = 50               Combine like terms
----   ----               Divide by 5 on both sides to get x alone
5      5
x = 10 green apples
4x = 4(10) = 40 red apples 

40 - 10 = 30. Suzanne bought 30 more red apples than green apples.
