Hello!
You can put in y for the first equation
2x - 3(x - 1) = -1
Distribute the -3
2x - 3x + 3 = -1
Combine like terms
-x + 3 = -1
Subtract 3 from both sides
-x = -4
Since x is negative we can multiply both sides by -1 to make x positive
x = 4
We can put x into the second equation to get y
y = 4 - 1
y = 3
The answers are x = 4 and y = 3
Hope this helps!
-4x - (-x) = -3x
Final Answer: -3x
Answer:
$0.82
Step-by-step explanation:
The full answer is 0.8225, although I believe that I was supposed to round it to the nearest hundredth, so I did that. What I did was I divided 3.29 by 4.
This requires converting the measurements which are in cm to m.
So you could have 180cm as 1.8m and 18cm as 0.18 (divide cm by 100 to get m)
Then you would take away the shortest, 0.18, from the longest, 1.8m to get
1.8 - 0.18 = 1.62
Rewrite : 
x 37
Simplify : 
x 37 = 702.531646...
Round to :
- Nearest whole number : 703
- 1 d.p : 702.5
- 2 d.p : 702.53
- 3 d.p : 702.532
