3x+7=-x-1
move -x to the other side
sign changes from -x to +x
3x+x+7=-x+x-1
3x+x+7=-1
4x+7=-1
move 7 to the other side
sign changes from +7 to -7
4x+7-7=-1-7
4x=-8
Divide by 4 for both sides
4x/4=-8/4
Answer: x=-2
Answer:
C and E
Step-by-step explanation:
Examples of binomials (two terms) :
9a - 5
3x + 6y
-4t + 2
Examples of monomials (one term) :
6x
10z
4a
Examples of trinomials (three terms) :
7y - 3x + 4
8x + 7 - 2a
4x + 9y + 5
(There can also be exponents and fractions in any kind: binomial, monomial, or trinomial.)
Answer:
No, -1/3 is not a solution
Step-by-step explanation:
See if it is a solution by plugging in -1/3 as v and seeing if the equation is correct:
9v - 2 = 3v
9(-1/3) - 2 = 3(-1/3)
-3 - 2 = -1
-5 = -1
-5 
-1
So, since the equation is incorrect, -1/3 is not a solution.
