Question

1. when using elimination, what is a common next step after adding the equations to eliminate one variable?

a. substitute back into the first equation
b. solve the resulting single-variable equation
c. rearrange the original equations
d. graph the resulting equation

Explanation:

When using elimination to solve a system of equations, after adding equations to eliminate one variable, the remaining equation has only one unknown. The immediate next step is to solve this single-variable equation to find the value of that variable, which can then be substituted back later to find the other variable. Options a, c, and d are not the standard common next step in this process.

Answer:

b. Solve the resulting single-variable equation
