2 answers:
Hello!
Answer:
Subtract 4 from both sides and. switch the inequality symbol.
The answer should be bold it in.
Answer should have a negative sign.
Step-by-step explanation:
First, you do is subtract by 4 from both sides of an equation.
And then, you simplify and solve.
, which is our final answer.
Hope this helps you!
Have a nice day! :)

Explanation:
The solution set for a system of equation is the set of points where the graphs of the equations intersect.
__
<h3>general case</h3>A system will have <em>one solution</em> if there is a <em>single point of intersection</em> of the graphs of the equations.
A system will have <em>no solutions</em> if the graphs have <em>no points of intersection</em>.
A system will have an <em>infinite</em> number of <em>solutions</em> if the graphs <em>intersect at an infinite number of points</em>.
_____
<h3>linear equations</h3>When the equations are linear equations, their graphs are straight lines. If the lines have different slopes, they must intersect at exactly one point: there will be one solution.
If the lines have the same slope, there are two possibilities:
- the lines are parallel -- no solutions
- the lines are coincident -- infinite solutions
The attached graph illustrates these cases.
- the red and blue lines are the graphs of a system of equations with one solution. Those lines have different slopes
- the blue and green lines are the graphs of a system of equations with no solution. Those lines are parallel.
- The red and (dotted) purple lines are the graphs of a system of equations with infinite solutions. Those lines are coincident.
