When using the substitution method to solve the system of equations, what is the result of the first step?
y = 2x + 4
2x + 3y = 8

B

Step-by-step explanation:

This is due to the fact that the first equation is saying it is equal to y so you replace the y variable with the equation

since y=2x+4 just substitute y with 2x+4

2x + 3(2x+4) = 8

so the answer is B

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.
