6x + y = -2
y = -3x + 1
Substitute the value of y in first equation,
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1
Now, Substitute it in 2nd equation,
y = -3(-1) + 1
y = 3+ 1 = 4
Coordinates would be: (-1,4) Mark that point and join with origin.
Hope this helps!
Answer:
Width = 7 inches
Length = 10 inches
Step-by-step explanation:
We know the 2(length + width) = 34, and we know that length = 3+width. Therefore, we can use substitution. 2(3+width+width) = 34, and we can see that the width is 7. The length of the rectangle is 7+3=10
4z - ( - 3 z)
= 4 z + 3 z = 7 z
5x - 1 = 15x - 101
101 - 1 = 15x - 5x
100 = 10x
100/10 = x
x = 10
How this has been solved is by bringing the equations with (x) to one side and solving them and solving the other numbers on the other side..
I think it would be 8-3, not 7. 8x - 2x + 5x = (8-5)x + 5x
