Answer:
(-1, -2) will be the solution.
Step-by-step explanation:
System of equations has been given as,
y = 3x + 1 ---------(1)
Input-output value table for the given line will be,
x -2 -1 0 1
y -5 -2 1 4
y = -x - 3 ----------(2)
Input-output value table for the given line will be,
x -2 -1 0 1
y -1 -2 -3 -4
By plotting the given coordinates we can draw the straight lines.
And the point of intersection (common point) of these lines will be the solution of the given system of equations.
Hence, (-1, -2) will be the solution.
Solving the inequality
we get value of x: 
Step-by-step explanation:
We need to solve the inequality
and find value of x.
Solving:

Multiplying -3 with the terms inside the bracket

Converting mixed fraction into improper fraction:

Adding 11.98x on both sides

Subtracting 24.6 on both sides:

Divide both sides by -0.02 and reverse the inequality i.e < sign is changed to > due to division of (-) sign.

So, solving the inequality
we get value of x:
