So you need the solve for x and y ?
from 8x-y = 10,
y = 8x -10
Plug this in other equation.
8x-10 = x^2 +12x + 30
Re-arrange and combine like terms,
x^2 +12x -8x +30+10 = 0
x^2 +4x +40 = 0
This does not have any real solutions.
So there are no real values of x and y satisfying the 2 equations.
Are you sure the question is correct? or if this question belongs to complex numbers topic?
Answer:
b = c(a - 6x )
Step-by-step explanation:
Given
6x + 
= a ( subtract 6x from both sides )
= a - 6x ( multiply both sides by c to clear the fraction )
b = c(a - 6x)
Answer: 0.60 gallon
Step-by-step explanation:
There are 12pounds in a standard US gallon.
12pounds= 1 gallon
5.2 pounds=?
5.2/12 × 1 gallon
0.624 gallon
Rounding to the nearest tenth =0.60
The last one with four boxes of x over 24
