Answer:
Step-by-step explanation:
Answer:
1 × (3x + 2y = 12)
2 × (4x - y = 5)
3x + 2y = 12
+ (8x - 2y = 10)
= 11x = 22
divide both sides by the coefficient of 'x' (11)
Therefore x = 2
put (x = 2) in equation 1
3(2) + 2y = 12
6 + 2y = 12
2y = 12 - 6
2y = 6
divide both sides by the coefficient of 'y'(2)
Therefore y = 3
The answer is C, the commutative property of multiplication.
Answer:
the answer is 17 or -11
Step-by-step explanation:
|x-3| - 4 = 10
|x-3| = 14
x-3 = 14 or -14
x = 17 or -11
