3x - 30 = 63
add 30 to both sides
3x = 93
divide by 3
x = 31

There were 16 more frogs in Green Pond than in Blue Pond. All the frogs from Blue Pond jumped into Green Pond. Now the total num

Dimas [21]

Let the number of frogs in the Blue Pond be x
Blue Pond = x
There were 26 more frogs in Green Pond than in Blue Pond
Green Pond = x + 26
There were 80 frogs altogether
x + x + 26 = 80
2x + 26 = 80
2x = 80 - 26
2x = 54
x = 27
x + 26 = 27 + 26 = 53

There were 53 frogs in the Green Pond originally.

Solve for x in both!!!!!

zvonat [6]

Answer:

$- 2(x - 2) - 4x = 3(x + 1) - 9x \\ - 2x + 4 - 4x = 3x + 3 - 9x \\ 9x - 3x - 2x - 4x = 3 - 4 \\ 9x - 9x = - 1 \\ 0x = - 1 \\ 0 = - 1$

So ; No solution

___o___o____

$5(x + 2) - 3 = 3x - 8x + 7 \\ 5x + 10 - 3 = - 5x + 7 \\ 5x + 7 = - 5x + 7 \\ 5x + 5x = 7 - 7 \\ 10x = 0 \\ \\ x = \frac{0}{10} \\ \\ x = 0$
