Answer:
choice 1) 2-4y
Step-by-step explanation:
from the answers available, you are looking for the expression for x to substitute into the first equation.
The second equation is: x+4y = 2
To convert x+4y = 2
subtract 4y from both sides of the equation:
x+4y-4y = 2-4y
simplified:
x = 2-4y
Since 5 is a factor of 10 and 15 (by guess and check with factors of 10 and seeing if they're factors of 15), we get 5(3x^2y^3+2xy^2z). Next, y^2 is in both - remember that when multiplying exponents, you add them up, so we end up with 5y^2(x^2y+2xz). Lastly, x (aka x^1) is in both, so we factor that out to end up with 5y^2x(xy+2z)
5.5 = 1.25x
1.25x = 5.5
x = 4.4
Answer : 4.4
