Answer:
x = 3
Step-by-step explanation:
Given the 2 equations
x + y = 3 → (1)
2x - y = 6 → (2)
Adding the 2 equations term by term eliminates the y- term, that is
3x = 9 ( divide both sides by 3 )
x = 3
Answer:
C) 21
Step-by-step explanation:
a² + 20² = 29² Use Pythagorean Theorem to solve for a
a² + 400 = 841 Solve for the exponents

a² = 441 Take the square root of both sides
a = 21
