Best ResponseYou've already chosen the best response.0c=4a3b9 a3b+2c=27 11a2b+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 4a3b9. c=4a3b9 a3b+2(4a3b9)=27 11a2b+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.
