Answer:
(-2, 1)
Step-by-step explanation:
Systems of equations can be solved using different methods. For this set of systems, you can multiply each equation by a factor in order to eliminate a variable and solve for the other variable:
-3(-5x - 3y = 7) or 15x + 9y = -21
5(-3x - 4y = 2) or <u>-15x -20y = 10</u>
-11y = -11
y = 1
Solve for x: -5x - 3 = 7
Add 3 to both sides: -5x -3 + 3 = 7 + 3 or -5x = 10
Solve for x: x = -2
(-2, 1)
Which Michael?? There are many many many Michaels in the world
First calculate that numeric value. It cannot be done immediately without calculations.
if 85% of studends liked mystery that means that 100% - 85% = 15% didnt like.
Those 15% are 30 that were given in text. Now we can calculate this using proportion:
15% 30 students
85% x students
we use cross multiplication:
15*x = 30*85
x = 30*85/15
x = 170
Answer is 170
0.25, 0.50, 0.74. It could be any of these numbers or any number between these numbers.
Answer:
The value of given expression for x = - 10 is - 81
Step-by-step explanation:
Given expression as :
3 
x - 2 
Or, 3 + x - 2 -
Or, 
x - 
or, 
Now for x = - 10
Or, 
∴ - 76 - 5
Or, - 81
Hence The value of given expression for x = - 10 is - 81 Answer
