Answer:
There is one possible solution
Step-by-step explanation:
Here, we want to get the number of solutions
We can proceed to solve the equation
we have two y values so we can directly equate the x parts
-2x - 4 = 3x + 3
3x + 2x = -3-4
5x = -7
x = -7/5
To get y, we substitute
We can only get one value of y too
So we have a point (x,y) as the solution to the system of equations
Answer: 296 or 592
Step-by-step explanation:
Answer:
2x+3
Step-by-step explanation:
Let x be the number
twice a number
2x
3 more than
2x+3
Just get only one of the placeholder on one side by itself
and do the same thing to both sides so it stays equal
3x+7=5x-21
add 21 to both sides
3x+28=5x
subtract 3x from obht sides
28=2x
sivide both sides by 2
14=x
The equation is 2x+3=7
2x +3=7
-3 -3
2x=4
divide both sides by 2
x=2
the answer is 2
