Answer:
<h2>2.3 < x < 8.7</h2>Step-by-step explanation:
Look at the picture.
We have a = 5.5, b = x and c = 3.2.
Substitute:
(1)
5.5 + x > 3.2 <em>subtract 5.5 from both sides</em>
x > - 2.3
(2)
5.5 + 3.2 > x
8.7 > x
(3)
x + 3.2 > 5.5 <em>subtract 3.2 from both sides</em>
x > 2.3
From (1), (2) and (3) we have:
2.3 < x < 8.7
Answer:
The solution is (1, -4)
Step-by-step explanation:
Given:
The pair of linear equations given are:
Subtracting equation (1) from equation (2), we get:
Now, plug in the value of 'x' in equation (1) and solve for 'y'. This gives,
Therefore, the solution is (1, -4)
