Assuming "E = f - 7" was meant to be "e = f - 7", substitute into 3e + 4f = −14:
3(f − 7) + 4f = −14
3f − 21 + 4f = −14
7f − 21 = −14
7f = 7
f = 1
Then e = f − 7 = 1 − 7 = −6.
Solution: e = −6, f = 1.
(If "E" was a different variable, tell me and I’ll solve that case.)
3(f − 7) + 4f = −14
3f − 21 + 4f = −14
7f − 21 = −14
7f = 7
f = 1
Then e = f − 7 = 1 − 7 = −6.
Solution: e = −6, f = 1.
