Question

# Find the solution of the system of equations.

y = 2x + 5

Hint:

### A graph is a geometrical representation of an equation or an expression. It can be used to solve by equating them to zero.

We are asked to solve the set of equation.

## The correct answer is: We are asked to solve the set of equation.

### Step 1 of 3:

The LHS of the set has the same value. Thus, equate the RHS of the set of equation to get the simplified equation.

Step 2 of 3:

Solve the simplified equation.

Find two numbers such that their product are : ab = 2(35) = 70 and the sum is a + b =3.

Here, the numbers are;

Thus, we have the solution as:

Step 3 of

Substitute the values of in any of the equation to get the values of y;

When x = -5,

when ,

Thus, the required solutions of the set of equation are (-5, -5) and (7/2,12).

A set of equations can also be solved by graphing them. Find the points where they intersect each other.
