Calculate the solution to these simultaneous equations using the substitution method: (1)(1)𝑒+𝑓e+f==1010 (2)(2)4𝑒−5𝑓4e−5f==−14−14
Question
Solution 1
The equations you provided seem to be formatted incorrectly. However, I'll assume you meant the following:
- e + f = 10
- 4e - 5f = -14
Here's how you can solve these equations using the substitution method:
Step 1: Solve the first equation for one variable. Let's solve for e: e = 10 - f
