Y= x + 1 and y = -1/2 x +4 what is the solution

x+1 = -1/2x+4

subtract x from both sides

1=-1 1/2x +4

subtract 4 from each side

-3 = - 1 1/2x

divide both sides by -1 1/2

x= 2

check the

2+1 =3

-1/2(2) +4 = 3

 so X = 2

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
