Answer:
3/11
Step-by-step explanation:
3/11~ 0.2727272727272727
The first step can be subtracting 2x from both sides leaving the equation with 6x + 3 = -15
Answer:
The answer looks to be 35! See where the line stops in bettween 30 and 40?^^
Hope this helps! Let me know if its correct or not!
a:
Just divide both sides by 7. Since 7 is positive, you don't need to change the inequality sign:
In set notation, we write
b:
Subtract 9 from both sides:
In set notation, we write
Let’s arrange the fist equation
x+y=12
2x+3y=29
Multiply equation 1 by 2
So it will be
2x+2y=24
Subtract eq 1 from eq 2
2x+3y=29
2x+2y=24
—————-
Y =5
Put value of y in eq 1
2x+2y=24
2x +10= 24
2x= 24-10
2x= 14
x=14/2
x=7
S.S= (7,5)
