Answer:x=7
y=2 5/6
Step-by-step explanation:
6(x-5)=12
6x-30=12
6x=12+30
6x=42
6x/6=42/6
x=7
6y-5=12
6y=12+5
6y=17
6y/6=17/6
y=2 5/6
If my math is right it would be y = 2x + 50<span>

Question 11
x+x+1/2x+1/2x=360
x+x+2/2x+=360
x+x+x=360
3x=360
x=120
Then substitute 120 in the place of x
x1=120
x2=120
1/2(120)=60
1/2(120)=60
To check your answer you can add 60+60+120+120 the should be equal to 360
Question 12
x+x+(x-45)+(x-45)+(x-45)=540
x+x+x-45+x-45+x-45=540
5x-135=540
5x=540+135
5x=675
x=675/5
x=135
Then substitute 135 in the place of x
x1=135
x2=135
135-45=90
135-45=90
135-45=90
To check your answer you can add 135+135+90+90-90 the should be equal to 540
