Answer:
x =√[y²+(27)²] = √[ z² - 3² +(27)²]
Step-by-step explanation:
step 1) x=√[y²+(27)²]
step 2)
We find y
z²=y²+3² → y² = z² - 3²
step 3) x = √[ z² - 3² +(27)²]
Answer:
(7,5)
Step-by-step explanation:
{2x + 4y = 34

Answer:
your question is unclear
Step-by-step explanation:
x+2y=4
-x -x
2y=4-x
divide by 2 to get y by it's self
y=2-(1/2x)
x+2y=4
-2y -2y
x=4-2y
