How do you solve with substitution
WebThe substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation. In this way, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. http://content.nroc.org/DevelopmentalMath/COURSE_TEXT2_RESOURCE/U14_L2_T1_text_final.html
How do you solve with substitution
Did you know?
WebTo solve a system of equations by substitution, solve one of the equations for one of the variables, and substitute this expression into the other equation. Then, solve the resulting equation for the remaining variable and substitute this value back into the original equation to find the value of the other variable.
