Give the steps you will use to separate the variables and then solve the equation 5m+17=17 plz explain
Answers
Answer:
Step-by-step explanation:
Solution 3:
(a) 3n - 2 = 46
(adding 2 both sides )
3n-2+2 = 46+2
3n= 48
dividing both sides by 3
\frac{3n}{3}=\ \frac{48}{3}
3
3n
=
3
48
n= 16
(b) 5m + 7 = 17
subtract 7 from both the sides
5m +7 -7 = 17 -7
5m = 10
dividing both sides by 5
\frac{5m}{5\ }=\ \frac{10}{5\ }
5
5m
=
5
10
m = 2
(c) \frac{20}{3}p\ =\ 40
3
20
p = 40
multiplying both sides by 3
\frac{20p}{3}\times3\ =\ 40\times3
3
20p
×3 = 40×3
20p = 120
dividing both sides by 20
\frac{20p}{20}=\ \frac{120}{20}
20
20p
=
20
120
p\ =\ \frac{12}{2}p =
2
12
p = 6
(d) \frac{3p}{10}\ =\ 6\
10
3p
= 6
multiplying both sides by 10
\frac{3p}{10}\times10\ =\ 6\times10
10
3p
×10 = 6×10
3p\ =\ 603p = 60
dividing both sides by 3
\frac{3p}{3}=\ \frac{60}{3}
3
3p
=
3
60
p = 20
Answer:
5m+17-7=17-17
5m=0
5m/5=0/5
m=0
