system of equations by substitution

What is the solution to this equation?

• one solution
• no solution
• infinite solutions
• none of these

Which choice shows substitution correctly?

y = 2x + 3

3x + 2y = 20

• 3x + (2x + 3) = 20

• 3x + 2y(2x + 3) = 20

• 3x + 2 (2x + 3) = 20

• y + 2x + 3 = 20
