Answer:
7y
Step-by-step explanation:
use distributive property:
4x+12y=6x-2y
2x=14y
x=7y
Answer:
x=6 and y=4
Step-by-step explanation:
Let's solve your system by elimination.
−x+3y=6; x+3y=18
−x+3y=6
x+3y=18
Add these equations to eliminate x:
6y=24
Then solve6y=24for y:
6y=24
(Divide both sides by 6)
y=4
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−x+3y=6
Substitute 4 for y in−x+3y=6:
−x+(3)(4)=6
−x+12=6 (Simplify both sides of the equation)
−x+12+−12=6+−12 (Add -12 to both sides)
−x=−6
(Divide both sides by -1)
x=6
Answer:
x=6 and y=4
Hope this helps! :)

Subtract the 5x to move it to the other side to get 3y = -5x + 15
Then, divide by 3 to get y by itself to get
y = -(5/3)x + 5
The y-intercept of the line 5x + 3y = 15 would be 5. Hope this helps you!

Answer:
a) -6
b) 3
-------
a) 12
b) -2
Step-by-step explanation:
The initial value of the line is always the constant at the end of the equation.
The rate of change is always the coefficient of x.
