The answer is x=-2

8(-2x+1=30-(-4+3x)
Distribute 8 through the parentheses
-16x+8=30-(-4+3x)
Add the number
-16x+8=34-3x
Move the variable to the left-hand side and change its sign
-16x+8+3x=34
Collect like terms
-13x=34-8
Divide both sides of the equation by -13
-13x/-13=26/-13

X=-2

Answer:

-2

Step-by-step explanation:

8 (-2x + 1) = 30 - (-4 + 3x)   Distribute

-16x + 8 = 30 + 4 - 3x  Combine like terms

-16x + 8 = 34 - 3x   Rearrange terms

-13x = 26 Divide by -13 on both sides

x = -2

Choice A: 3 nights and one meal for $ 250
Simora [160]
Let x be the price for each night and y be the price for each meal. Then, express the statements into mathematical equations:

Choice A: 3x + y = 250
Choice B: 3x + 6y = 330

Subtract both equations, the difference would be -5y = -80

-5y = -80
y = -80/-5
y = $16 per meal

3x + y = 250
3x + 16 = 250
3x = 250 - 16
3x = 234
x = 234/3
x = $78 per night

The answer is D.
