Answer:
2(3x+y=4)
1(x+2y=-2)
6x+2y=8
<u>(-) x+2y=-2</u>
<u>5x=10</u>

x=2
x+2y=-1
2+2y=-1
<u>-</u><u>2</u><u> -</u><u>2</u>
<u>2y=-</u><u>3</u>
2
y=-3/2
Step-by-step explanation:
- multiply the first equation by 2 to make y equal to each other.
- subtract to eliminate y
- divide by 5 to get x
- take one of the equations
- replace x by 2 to solve for y
14/15 - 5/12
Common denominator is 60.
56/60 - 25/60
= 31/60 as fraction.
= 0.516 as decimal.
