Answer:
a) y=-4-2x
b) since y=-4-2x equate it to x+y=-7 to be
x-4-2x=-7
x-2x=-7+4
-x=-3
x=3
c)if x=3 then y=-4-2(3)
y=-10
Answer:
x=2
Step-by-step explanation:
4x-6=6-2x
(add 2x and 6 to both sides)
6x=12
(divide by six)
x=2
Double Check:
4(2)-6=2
6-2(2)=2
4(2)-6=6-2(2)
The Crayola crayon company can make 9000 crayons in 15 minutes.
We first want to subtract 19 from both sides and lastly subtract 17 minus 19 and we get our answer.
19 + -2 = 17 is true and correct since if u add 19 plus negative two u can just do 19 minus two and still receive 17.
x = -2.
2, –6 is the correct answer
