Answer:
x = 2 y= 1
Step-by-step explanation:
Solve the system by elimination by stacking the equations lining up the variables.
x + 3y = 5
-x - y = -3
Next, add each of the like terms.
x + 3y = 5
+ -x - y = -3
-----------------------
0x + 2y = 2
y = 1
Then substitute y = 1 into one of the equations.
x + 3(1) = 5
x + 3 = 5
x = 2

Answer:C
Step-by-step explanation:
<span>It's letter C
Addition, you can have 6 + 107 = 113 </span>
<span>Commutative Property by moving: 107 + 6 = 113 </span>
<span>Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 </span>
<span>Distributive Property by allotting: 2 (3) + 107 = 113 </span>
<span>Multiplication, you can have 6 x 107 = 642 </span>
<span>Commutative Property by moving: 107 x 6 = 642 </span>
<span>Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 </span>
<span>Distributive Property by allotting: 2(3) x 107 = 642<span>
</span></span>
