Simplifying -2x + -3y = -7

Solving -2x + -3y = -7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation. -2x + -3y + 3y = -7 + 3y

Combine like terms: -3y + 3y = 0 -2x + 0 = -7 + 3y -2x = -7 + 3y

Divide each side by '-2'. x = 3.5 + -1.5y Simplifying x = 3.5 + -1.5y

If 3 is added to twice a number, the result is 17. Find the number
Crank

Answer:

7

Step-by-step explanation:

The text of this expression is:

"If 3 is added to twice a number, the result is 17. Find the number"

Let's call x the number we want to find.

Twice the number is equal to

2x

So, if we add 3 to 2x, we get

3+2x

And we know that this is equal to 17:

3+2x=17

Now we can solve the equation to find x: first, we subtract 3 from both sides

3+2x-3=17-3\\2x=14

Now we divide both sides by 2:

\frac{2x}{2}=\frac{14}{2}\\x=7

The table can be used to determine the solution to the system of equations, 2y − x = 8, and y − 2x = −5. Which solution can be u
SIZIF [17.4K]
The answer is (6, 7)

This is the system of two equations:
<span>2y − x = 8
y − 2x = −5
_____
Express the second equation in the term of y:
2y - x = 8
y = 2x - 5
_____
Substitute y in the first equation:
2(2x - 5) - x = 8
4x - 10 - x = 8
4x - x = 10 + 8
3x = 18
x = 18/3
x = 6

Since x = 6 and y = 2x - 5, then:
y = 2 * 6 - 5 
y = 12 - 5
y = 7

Therefore, (x, y) = (6, 7)</span>
