# Question #46dc6

##### 1 Answer

Solutions:

#### Explanation:

We can find the solution (common points of each equation) algebraically or graphically. To make a graph, simply make a table with 'x', 'y1' (from expression1), 'y2' (from expression2) and then plot them on graph paper.

Algebraically, we can use the first equation to set y = x + 4 and then substitute it into the second equation.

For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by:

In this case, a = 3, b = 4 and c = 1

We can see that the algebraic solution may be more precise than we could obtain visually from a graph.

CHECK: x = -1 , y = 3
