c=-4a-3b-9 a-3b+2c=27 11a-2b+3c=28 Replace all occurrences of c with the solution solution The value of a variable that makes an equation true. found by solving the last equation equation A mathematical statement that says two expressions have the same value; any number sentence with an = . for c. In this case, the value substituted is -4a-3b-9. c=-4a-3b-9 a-3b+2(-4a-3b-9)=27 11a-2b+3c=28 Replace all occurrences of c with the solution solution The value of a variable that makes an equation true. found by solving the last equation equation A mathematical statement that says two expressions have the same value; any number sentence with an = . for c.
