Answer:
x - 6
Step-by-step explanation:
I am unfamiliar with such algebra tiles, but logically that set of tiles tells me :
1 x, -1, -1, -1, -1, -1, -1
so,
1×x + 6×(-1) = x - 6
1 switch sides
(x-4)=0
add four to both sides
x-4+4 = 0+4
simplify
x = 4
First you need to find the y-intercept, which is y = -1
Next is we need to find the slope of the line > you are going to have to do this by finding to clear point
The ones that I will be using are: (3, 1); (6, 3) (You could take any points)
Now using the slope formula we could find m.
m = y2-y1 / x2-x1
(1 - 3) / (3 - 6) = m
-2 / -3 = m
m = 2/3
Using the linear function format: y = mx + b
Therefore the equation of the line is y = 2x/3 -1
If I were you, I would search it up on VirtualNerd but you first undo using the opposite of PEDMAS and if you divide or multiply with a negative integer, the direction of the inequality thing in the middle of the equation switches directions.
{4x + 4y = 20 | ÷4<span>
{2x -2y = -18 | </span>÷2
{x + y = 5
{x -y = -9
--------------
2x = -4
x = -2
x + y = 5
-2 + y = 5
y = 5 + 2
y = 7
The answer is (-2, 7)
