The sum of x and y is 280. If x + 8 is y, when will the value of x be the same for both equations?

x = 136, y = 144

Step-by-step explanation:

x+y = 280

y = x +8

use substitution

x + x+8 = 280

2x = 272

x = 136

y= 136+8 = 144

the answer is x=136

Step-by-step explanation:

x + y = 280

x + 8 = y (substitute this expression for y)

x + (x + 8) = 280

2x + 8 = 280

2x = 272 -> x = 136

to find y:

x + 8 = y

136 + 8 = y

144 = y

CHECK:

136 + 144 = 280

yes

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
