Answer:
you just need to devide by 2 the second equation
Step-by-step explanation:
- -x + y = 2 (you leave it as it is)
- 2x + 4y =32 => 2x/2 +4y/2 = 32/2
=> x + 2y =16
we can devide or multiply in an equation by any number we want, as long as we do it to every term.
Answer:
A = ± 
Step-by-step explanation:
Given
b²A² - 3g = q ( add 3g to both sides )
b²A² = q + 3g ( divide both sides by b² )
A² = 
( take the square root of both sides )
A = ±
