-x+3y=6 X+3y=18 elimination
hram777 [196]

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! :)

A straight line with x-intercept -6 is parallel to the line 5x+3y=15. Find the y-intercept of that line
jeyben [28]
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!
