Answer:
x = 1, y = 2, z = 4
Step-by-step explanation:
(x + 4y – z = 5
2(3x – 2y + 2z = 7
)
6x - 4y + 4z = 14
7x + 3z = 19
3(2x – z= -2)
6x - 3z = -6
13x = 13
x = 1
6(1) - 3z = -6
-3z = -12
z = 4
(1) + 4y - 4 = 5
4y = 8
y = 2

Step-by-step explanation:
<u>Step 1: Define Equation</u>
2(x + 4) = 4x + 3 - 2x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 2x + 8 = 4x + 3 - 2x + 5
- Combine like terms: 2x + 8 = 2x + 8
- Subtract 8 on both sides: 2x = 2x
- Divide 2 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>.
∴ x = infinite amount of solutions
The SI system is the Internation System of Units which contains kg, liters, cm, etc.
The answer is 10. Example: meters and decimeters, decimeters to centimeters, centimeters to millimeters
If you are looking for the total number of flowers the equation should be 22 multiplied by 4 to get 88
