Solve the simultaneous equations by using the substitution technique. The questions in this section will probably be easier to solve by using the elimination technique. However, I think that it is a good idea to practice using the substitution technique before we use it on simultaneous equations that contain quadratic terms.

*c*+ 7*d*= 16*c*– 4*d*= 143) 3

*e*+ 16 = 11 +*f*2

*f*+ 2*e*= -14
