Answer:
23 + b ≤ -276
Step-by-step explanation:
In this exercise, you're required to write an algebraic expression for the word problem. Thus, you'll write out a mathematical equation using the given values and unknown variable.
Translating the word problem into an algebraic expression, we have;
23 + b ≤ -276
Simplifying further, we have;
b ≤ -276 - 23
b ≤ -299

Please solve with elimination i really need the help!!
please show work
Answer:
x = 6
y = 7
Step-by-step explanation:
Here, (10x - 8y = 4) and (- 5x + 3y = - 9) are two given equation
Now, Name the equation
10x - 8y = 4
take 2 as common we get
2(5x - 4y = 2)
5x - 4y = 2 ...(1)
- 5x + 3y = - 9 ...(2)
Now, Subtract (1) from (2)
5x - 4y = 2
- 5x + 3y = - 9
————————
- y = - 7
y = 7
Now,Put the value of y in equation (1) we get
5x - 4y = 2
5x - 4(7) = 2
5x - 28 = 2
5x = 28 + 2
5x = 30
x = 30÷5
x = 6
Thus,The value of xis6and yis7
FORVERIFICATIONONLY:
5x - 4y = 2
5(6) - 4(7) = 2
30 - 28 = 2
2 = 2
- 5x + 3y = - 9
- 5(6) + 3(7) = - 9
- 30 + 21 = - 9
-9=-9
Hence,L.H.S = R.H.S
