Answer:
Step-by-step explanation:
Let's solve your system by substitution.
32=4(n−5);−s+11=17
Rewrite equations:
32=4n−20;−s+11=17
Step: Solve 32=4n−20 for n:
32=4n−20
32+−4n=4n−20+−4n(Add -4n to both sides)
−4n+32=−20
−4n+32+−32=−20+−32(Add -32 to both sides)
−4n=−52
−4n/
−4
=/
−52/
−4
(Divide both sides by -4)
n=13
Step: Substitute 13 for n in −s+11=17:
−s+11=17
−s+11=17
−s+11+−11=17+−11(Add -11 to both sides)
−s=6
−s/
−1
=
6/
−1
(Divide both sides by -1)
s=−6
Answer:
n=13 and s=−6
