If you’re simplifying then you’re answer is 2.2w-0.5 combine like terms would be the same answer !
Answer:
Since the first equation x is equal to 4y - 9, it is easier to substitute 4y - 9 in for x in the second equation.
x = -1 y = 2
Step-by-step explanation:
Since the first equation x is equal to 4y - 9, it is easier to substitute 4y - 9 in for x in the second equation. That would give you
4y - 9 + 4y = 7
8y - 9 = 7
8y = 16
y = 2
x = 4y - 9 = 4(2) - 9 = 8 - 9 = -1
It is always a good idea to check and see if your results satisfy the two equations
Answer:
