E Value of the Expression a. 50 times the sum of 64 and 36. 50 x(64+36)
Answer:
x=3, y=1. (3, 1)
Step-by-step explanation:
6x+2y=20
0.5x-0.5y=1
-----------------
6x+2y=20
1/2x-1/2y=1
----------------
6x+2y=20
2(1/2x-1/2y)=2(1)
------------------------
6x+2y=20
x-y=2
-------------------
6x+2y=20
x=y+2
---------------
6(y+2)+2y=20
6y+12+2y=20
8y+12=20
8y=20-12
8y=8
y=8/8
y=1
x=1+2=3
x=3, y=1.
