Question

If anyone can answer all these thanks

1. 4x+3=23
2. 24x - 18=30
3.160+10n=220
4.51=30+3n
5.6y+85=157

Answer 1

1) x = 5

2) x = 2

3) n = 6

4) n = 7

5) y = 12

Step-by-step explanation:-

1)

`4x+3=23`

→
`4x = 23 - 3`

→
`4x = 20`

→
`x = (20)/(4)`

→
`x = 5`

Hence, value of x is 5

2)

`24x - 18=30`

=>
`24x = 30 + 18`

=>
`24x = 48`

=>
`x = (48)/(24)`

=>
`x = 2`

Hence, value of x is 2

3)

`160+10n=220`

`→10n = 220 - 160`

`→10n =60`

`→n = (60)/(10)`

`→n = 6`

Hence, value of n is 6

4)

`51=30+3n`

`→51 - 30 = 3n`

`→21 = 3n`

`→(21)/(3) = n`

`→n = 7`

Hence, the value of n is 7

5)

`6y + 85=157`

`→6y = 157 - 85`

`→6y = 72`

`→y = (72)/(6)`

`→y = 12`

Hence, value of y is 12
