8x+15=3x-20 how do you do this

8x + 15 = 3x - 20

Add 20 to both sides. It should become

8x + 35 = 3x

Then minus 8x on both sides, which is now

35= -5x

What biome is New Caledonia considered?

Solve using elimination, 2x+5y=2 3x-5y=53

(+) 3x - 5y =53

-------------------------

5x + 0 = 55

Then finish it.

5x = 55

x = 11

Substitute x = 11,

2(11) + 5y = 2

22 - 2 + 5y = 0

20 + 5y = 0

5y = -20

y= -4

Solve using substitution, y=2x+5 y=6x+1

y = 6x+1

Just substitute.

y = 2x+5

6x+1 = 2x+5

6x-2x = 5-1

4x = 4

x = 1

Then, insert x = 1 into one of the equation. Let's say I choose number one.

y = 2x+5

y = 2(1) + 5

y = 7
