Question

The equation 2x = 50 – 3x can be solved by graphing y = 2x and y = 50 – 3x. Use the drop-down menu to complete the statement to explain why a graph can be used to solve this equation.

Answer 1

See below

Explanation:

By using a graph and plotting the two equations, you can find where they intersect and that will be the solution. You can also simply solve it algebraically:

2x = 50 - 3x

5x = 50

x = 10

y = 2x = 2(10) = 20

y = 50-3x = 50-3(10) = 50-30 = 20
