Eight times the result of subtracting 3 from a number is equal to the number increased by 25 what is the number

7

Step-by-step explanation:

Given: Eight times the result of subtracting 3 from a number is equal to the number increased by 25 what is the number.

Let x be the number.

According to the question, we have

8(x-3)=x+25

⇒8x-24=x+25  [open parenthesis]

⇒8x-24-x=25  [Subtract x from both sides ]

⇒7x-24=25

⇒7x=49  [Add 24 to both sides ]

⇒x=7  [divide both sides by 7 ]

Therefore, the number is 7.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
