Step-by-step explanation:
Answer:
18 times the first equation and 8 times the second equation
Step-by-step explanation:
we have
------> first equation
------> second equation
step 1
Multiply the second equation by 8 both sides to remove the fraction in the variable y
step 2
Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y


step 3
Adds the new equation 1 and equation 2

The y-term is eliminated
therefore
The answer is
18 times the first equation and 8 times the second equation
The answer is 16x because if you add 10 and 2 you get 12 then add 4 you get is 16 but you need to multiply by x so you write it as 16x
