Hello from MrBillDoesMath!
Answer:
x >= 7
Discussion:
x + 5 >= 12 => add -5 to both sides
x + 5 -5 >= 12 - 5 => as 5-5 = 0 and 12 =5 = 7
x >= 7
Thank you,
MrB
The missing numbers are 18 and -12
Step-by-step explanation:
Let us explain the meaning of coincidental system of equations
- If an equation of a line is ax + by = c, and we multiply or divide all the terms by the same number n, then we will have another equation nax + nby = nc, which represents the same line as the first equation
- The two equations ax + by = c and nax + nby = nc form a coincidental system of two linear equations
- This system has many solutions (all the points on the line)
∵ 2x + 3y = -17 is one equation in a coincidental system of two
linear equations
- To find the other equation multiply each term by n
∴ The second equation is 2nx + 3ny = -17n
∵ The other equation is _y = _x - 102
∵ The other equation is 2nx + 3ny = -17n
- Compare them to equate the like terms
- Subtract both sides by 2nx to have the same form of the other
equation
∴ 3ny = -2nx - 17n
- Equate the numerical terms
∴ -17n = -102
- Divide both sides by -17
∴ n = 6
- Substitute the value of n in the other equation
∴ 3(6)y = -2(6)x - 17(6)
∴ 18y = -12x - 102
∴ The other equation is 18y = -12x - 102
The missing numbers are 18 and -12

Sum: 
<u>Step-by-step explanation:</u>
While translating the problems into mathematical expression or mathematical expression in English, Kind of Expression can be used. Mostly in the algebraic parts.
Quotient: It represents that one value is divided by the another value. It is also known as the ratio.
i.e: .
Product: It means multiplying either a known value and unknown variables or both unknown variables.
i.e.: 8b.
Sum: It means adding either a known value and unknown variables or both unknown variables.
i.e.:
