The principal of a high school spent 1700 for X desk each and Y chairs at $25 each if he had bought half the number of desk in t

KatRina [158]

Answer:

25X + 25Y = 1700

25X + 100Y = 3200

Step-by-step explanation:

Given that the principal of a high school spent $1700 for X desk and Y chairs at $25 each. Then, the equation will be

25X + 25Y = 1700 ....... (1)

If he had bought half the number of desk in twice the number of chairs he would have spent 1600. That is

25(X/2) + 25(2Y) = 1600

25X/2 + 50Y = 1600

Find the LCM and cross multiply

25X + 100Y = 3200 ........(2)

X +5+11x=12x+Y It says find the value of y that makes each equation true for all values of

sladkih [1.3K]

X + 5 + 11x = 12x + y

Simplify: 12x + 5 = 12x + y (We are adding x and 11x on the left side)

Subtract 12x from each side makes each zero.

5 = y

So we can plug in and test. I'm picking two random numbers to plug in for x. 10, and 82

x = 10, y = 5
10 + 5 + 11(10) = 12(10) + 5
125 = 125

x = 82, y = 5
82 + 5 + 11(82) = 12(82) + 5
989 = 989

So we verified y = 5
