Solve this equation. y=x+3 and 4x+y=18

y=x +3

y=-4x +18

Therefore

x+3=-4x + 18

5x=18-3

5x=15

x=3

y=x +3

y=3+3

y=6

y = 18 - 4x

18 - 4x = x + 3

-5x = -15

x = 3

y = 3 + 3

y = 6

Step-by-step explanation:

astronomers is your final answer! : )

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
