Answer 1

5x-4x=10-7
x=3

6y-5y=5+5-9
y=1

11p+9p-2p=100-32-42
18p=26
p=1,(4)

Answer 2

Equation 1: 5x - 4x + 7 = 10

To find the roots of this equation, we need to simplify it first. Combining like terms, we have:

x + 7 = 10

Next, we isolate the variable x by subtracting 7 from both sides:

x = 10 - 7

Simplifying further, we get:

x = 3

Therefore, the root of the equation 5x - 4x + 7 = 10 is x = 3.

Equation 2: 9y + 6u - 5 - 5y = 5

To find the roots of this equation, we need to simplify it first. Combining like terms, we have:

4y + 6u - 5 = 5

Next, we isolate the variable y by subtracting 6u and 5 from both sides:

4y = 5 - 6u + 5

Simplifying further, we get:

4y = 10 - 6u

Finally, we divide both sides by 4 to solve for y:

y = (10 - 6u) / 4

Therefore, the root of the equation 9y + 6u - 5 - 5y = 5 is y = (10 - 6u) / 4.

Equation 3: 11p + 42 - 2p + 9p = 100 - 32

To find the roots of this equation, we need to simplify it first. Combining like terms, we have:

18p + 42 = 68

Next, we isolate the variable p by subtracting 42 from both sides:

18p = 68 - 42

Simplifying further, we get:

18p = 26

Finally, we divide both sides by 18 to solve for p:

p = 26 / 18

Simplifying the fraction, we get:

p = 13 / 9

Therefore, the root of the equation 11p + 42 - 2p + 9p = 100 - 32 is p = 13 / 9.
