Question

# Rewrite the equation as a system of equations, and then use a graph to solve.

Hint:

## The correct answer is: We are asked to rewrite the equation as system of equations and graph them to solve it.

### Step 1 of 3:Equate each side of the equation to a new variable, y :Thus, we get a system of equation.Step 2 of 2:Consider the equation, y = 2x2 + 3x. Find three solutions for the equation.when x = 0,when x = -1,when x = 1,Thus, the points are; (0, 0) )(-1, -1) and (1,5)Consider the equation y = 2x+y and find two solutions.when  x = 0,when x = 1,Thus, the required points are; (0,1) and (1, 3)Step 3 of 3:Plot the points and join them to get the respective graphs.Here, they graphs intersect at two point; (-1 -1) and (0.5, 2). This means that the solutions of the system of equation are (-1 -1) and (0.5, 2).

Solutions of a set of equation can be found by graphing the equations and finding the intersecting points. The points where they intersect are the solutions.
