the sum of 2 number is 64,twice the large number plus five times the smaller number is 20 find the 2 numbers

The two numbers are:  - 36 and 100

Step-by-step explanation:

let the smaller number = x, let the larger number = y

then...

x + y = 64

5x + 2y = 20

use substitution:  y = (64 - x)

5x + 2(64 - x) = 20

3x = 20 - 128 = - 108

x = - 36

So the two numbers are:  - 36 and 100

Tell me If I'm wrong

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
