Answer:

(-6,8)

Step-by-step explanation:

2x + 9y = 60

-9x + y = 62

y = 62 + 9x

2x + 9(62 + 9x) = 60

2x + 558 + 81x = 60

83x = -498

x = -6

y = 62 + 9(-6) = 8

What is the value of x?

tigry1 [53]

Answer:

x = 61

Step-by-step explanation:

To answer this question, we combine like terms:

44 + 59 + 74 = 177

The total will have to be 360, so....

177 + x + x + x = 360

177 + 3x = 360

360 - 177 = 183

So, 3x = 183

183 / 3 = 61

So, x = 61!
