-x+3y=6 X+3y=18 elimination

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! :)

Find the value of x and y. SHOW YOUR WORK
Leona [35]

Answer:

x=21, y= 35

Step-by-step explanation:

3x+7=5x-35

(subtract seven from -35)

3x=5x-42

(subtract 5 from 3)

-2x=-42

(-42/-2= positive number)

x=21

y+75=3y+5

(subtract 75 from 5)

y=3y-70

(subtract 3y from y)

-2y=-70

y=35
