Answer : x=3
Step-by-step explanation:
Explanation:
2x+3=9
We want to find the variable x, so we have to make it alone. To do so, first subtract 3 from both sides of the equation:
2x+3 − 3=9 − 3
2x=6
Now divide both sides by 2:
2x2=62
So the final answer is:
x=3
Answer:
x is equal to 7
Step-by-step explanation:
Because the two horizontal lines are parallel, we know that the angles at which they intersect the diagonal line will be identical.
We also know that on either side of the diagonal line, the sum of the angles between that and either of the horizontal lines will be 180.
In short, we know that the two values given have a sum of 180. With that we can quickly solve for x:
(x + 67) + (x + 127) = 180
2x + 194 = 180
2x = -14
x = 7

Answer:
Option D is correct.
x y
0 5
1 10
2 20
Step-by-step explanation:
Given the equation: 
.....[1]
Here, x is the input variable and y is the output variable.
For x =0
Substitute in equation [1]; we have;
For x = 1
Substitute in equation [1]; we have;
For x =2
Substitute in equation [1]; we have;
Therefore, the table values which is correct for the equation is;
x y
0 5
1 10
2 20
