2-60.

Use substitution to find *y*.** **Homework Help ✎

Wherever *x* occurs in the problem, write the given number instead.

*y*= 3 + 8.5*x*, when*x*= −4Remember to include the negative sign when you substitute for

*x*.−31

*y*=*x*− 15, when*x*= 2.65What is 15 subtracted from 2.65?

*y*= (*x*− 5)(*x*+ 2), when*x*= 3Simplify the expression inside the parentheses before multiplying.

*y*+ 6.2*x*= −13, when*x*= −4*y*+ 6.2(−4) = −13*y*+ (−24.8) = −13*y*− 24.8 = −13*y*= 11.8
