Answer:
x = - 4, y = 7
Step-by-step explanation:
Given the 2 equations
- 7x - 2y = 14 → (1)
6x + 6y = 18 → (2)
Multiplying (1) by 3 and adding to (2) will eliminate the y- term
- 21x - 6y = 42 → (3)
Add (2) and (3) term by term to eliminate y
- 15x = 60 ( divide both sides by 15 )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (2)
6(- 4) + 6y = 18
- 24 + 6y = 18 ( add 24 to both sides )
6y = 42 ( divide both sides by 6 )
y = 7
Answer:
A: 4
Step-by-step explanation:
So first you can move the 2^-5 to the denominator, making the equation (2^2) (4^3) / (2^5) (2)
Then simplify the terms so you end up with (4)(64) / (32) (2)
Then multiply the denominator so you end up with (4) (64) / (64)
Since both the denominator and numerator have 64, those cancel out leaving you with 4
