Answer:
Step-by-step explanation:
191.2 = 2.3L +65.5
191.2 - 65.5 = 2.3L {Subtract 65.5 from both sides}
125.7= 2.3L
L = 125.7/2.3
L = 54.65
-1 - -1.
-1 + 1.
0.
The answer is 0.
I don't have the ranges of numbers to see which range so clearly it's impossible to answer
Answer:
(2, 1 )
Step-by-step explanation:
Given the 2 equations
y = 6x - 11 → (1)
- 2x - 3y = - 7 → (2)
Substitute y = 6x - 11 into (2)
- 2x - 3(6x - 11) = - 7 ← distribute and simplify left side
- 2x - 18x + 33 = - 7
- 20x + 33 = - 7 ( subtract 33 from both sides )
- 20x = - 40 ( divide both sides by - 20 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 6(2) - 11 = 12 - 11 = 1
Solution is (2, 1 )
