In 3x + 2y = 10 and x - 5y = 18, which variable would be simplest to isolate first?

• The x in the first equation

• The y in the first equation

• The x in the first equation

• The x in the second equation

y = 2x + 5

2x + 2y = 4

When solving the system of equations using substitution, the equation will be...

• y = 2(2x + 2y - 4) + 5

• 2x + 2y = 2x + 5

• 2(2x + 5) + 2y = 4

• 2x + 2(2x + 5) = 4

The ordered pair that satisfies BOTH equations in the system is called the _____________________

• system of equations
• function
• graph
• solution
