As per the system of linear equations concept, the solution of x is -1.282
Linear equations:
Linear equation is referred as the algebraic equation in which each term has an exponent of 1 and when graphed, the result is always a straight line.
Given,
Here we have the equations -4x - 1 = 5ˣ + 4
Now, we need to find the value of x by using the graph.
In order to plot the graph for the given linear equation,
First, we have to split the equation into two,
Like the following:
y = -4x - 1
y = 5ˣ + 4
Now, we plot the graph of both equations
Then we get the graph like the following.
Where the red line represents the equation y = -4x - 1 and the green line represents the equation y = 5ˣ + 4.
While we looking into the graph, we have identified the solution is,
x = -1.282
Therefore, the solution of x is -1.282
