Answer:
x = 2
y = 1
Step-by-step explanation:
y = 5 - 2x (1)
3x - 2y = 4 (2)
From (1), substitute in (2)
3x - 2(5 - 2x) = 4
3x - 10 + 4x = 4
Collecting like terms
3x + 4x = 4 + 10
7x = 14
x = 2
Since x = 2
Therefore
y = 5 - 2x
y = 5 - 2(2)
y = 5 - 4
y = 1

Step-by-step explanation:
Heres what you have to do. once you get the answer of the equation use a number line to draw how you got the answer ik it might not help alot but i hope it gave u an idea!!
Answer:
I think difference between values on y-axis should be same. For eg: 100,200,300,400,500......
Answer:
Question 39: False
Question 43: True
Step-by-step explanation:
<u>Question 39</u>
|-4| is a solution of x ≤ 4
|-4| ⇒ This mean the absolute value of 4. The sign s are neglected.
So, |-4| is not a solution of x ≤ 4.
<u>Question 43</u>
The point (5, -1) is a solution of the equation: y = 2x − 11.
To prove this we are to substitute the point (5, -1) in the equation y = 2x − 11.
y = -1 and x = 5
y = 2x − 11 ⇒ -1 = 2(5) -11
-1 = 10 - 11
-1 = -1
