Find the solution of the system of equations.
y = 3x - 5
Hint:
Hint:
An expression of the form (x2 - a2) can be simplified into (x - a) (x + a). The solutions can be found by equating them to zero.
We are asked to solve the set of equation.
Substitute the values of in any of the equation to get the values of y.
The correct answer is: We are asked to solve the set of equation.
Step 1 of 3 :
The LHS of the given set has the same value. So, equate the RHS of the set. Thus, we get:
Step 2 of 3 :
Solve the simplified equation;
Step 3 of 3:
Substitute the values of in any of the equation to get the values of y.
when x = -1,
when x = 1,
Thus, the required solutions are ( -1,-8) and (1,-2)
You could solve a set of equations by graphing them. The points where the graphs intersect are the solutions.
