First person with ansers gets branily neeed asap plz 2. solve each given equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither. (a) 6x + 4x − 6 = 24+ 9x (b) 25− 4x = 15−3x +10− x (c) 4x +8 = 2x +7+ 2x − 20

a. 6x + 4x - 6 = 24 + 9x

Combine like terms.

10x - 6 = 24 + 9x

Add 6 to both sides.

10x = 30 + 9x

Subtract 9x from both sides.

There is one solution, and it is equal to 30.

b. 25 - 4x = 15 - 3x + 10 - x

Combine like terms.

25 - 4x = 25 - 4x

Cancel like terms.

There are infinite solutions, as both lines are the same.

c. 4x + 8 = 2x + 7 + 2x - 20

Combine like terms.

4x + 8 = 4x - 13

Cancel like terms.

There are no solutions, and the equation is false.

Lines are parallel.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
