Answer:
1) [tex]y=17-5x[/tex]
2) [tex]y=9x+7[/tex]
3) [tex]y=x-3[/tex]
4) [tex]y=12x+4[/tex]
Step-by-step explanation:
1) We have [tex]y+5x=17[/tex]
subtract 5x from both sides to get
[tex]y=17-5x[/tex]
2) We have [tex]4y-36x=28[/tex]
Add 36x to both sides to get:
[tex]4y=36x+28[/tex]
Divide through by 4 to get:
[tex]y=9x+7[/tex]
3) We have [tex]8x-11=13+8y[/tex]
Subtract 13 from both sides of the equation.
[tex]8x-24=8y[/tex]
Divide through by 8
[tex]x-3=y[/tex]
Swap both sides of the equation
[tex]y=x-3[/tex]
4) We have 6+y=10+12x
Subtract 6 from both sides of the equation
[tex]y=10-6+12x[/tex]
[tex]y=4+12x[/tex]
[tex]y=12x+4[/tex]
