Question

I need answers please l don’t understand please show working to help me please

Answer 1

1)

`10t=8+9t+5`

`10t=9t+13`

`10t-9t=13`

`t=13`

2)

`-12=3x`

`-4=x`

`x=-4`

3)

`-5+3x=x+9`

`3x=x+9+5`

`3x=x+14`

`3x-x=14`

`2x=14`

`(2x)/(2)=(14)/(2)`

`x=7`

4)

`10a=-15+7a`

`10a-7a=-15`

`3a=-15`

`(3a)/(3)=(-15)/(3)`

`a=-5`

5)

`7x=6x+27`

`7x-6x=x`

`x=27`

6)

`-3x-6=-5x+10`

`-3x=-5x+16`

`-3x+5x=16`

`2x=16`

`(2x)/(2)=(16)/(2)`

`x=8`

7)

`2y-4=10y+12`

`-4=8y+12`

`-4-12=8y`

`-16=8y`

`(8y)/(8)=(-16)/(8)`

`y=-2`

8)

`-9a+1=6-4a`

`1=6+5a`

`1-6=5a`

`-5=5a`

`(5a)/(5)=(-5)/(5)`

`a=-1`

Hope this helps!
