Answer:
x = 2
Step-by-step explanation:
Given
1 + x = 7 - 2x ( add 2x to both sides )
1 + 3x = 7 ( subtract 1 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2

Since the value of b is 5, hence the equation of the horizontal line is x = 5
<h3>Equation of a line</h3>
A line is defined as the shortest distance between two points. The given line on the xy plane is a horizontal line.
The equation of a line is expressed as y = mx + b where;
m is the slope
b is the y -intercept
The equation of a horizontal line on the other hand is expressed as x = b
where b is the point where the horizontal line crosses the y-axis.
Since the value of b is 5, hence the equation of the horizontal line is x = 5
