Answer:
x = 0/2
x = 0
Step-by-step explanation:
4(x+8)-2(x-7) = 46
Expanding the brackets
4x +32 - 2x +14 = 46
2x + 46 = 46
2x = 46-46
2x = 0
x = 0/2
x = 0
It is $2.25 for 1 pound of apples and $9 for 4 pounds of apples

Step-by-step explanation:
<u>Step 1: Define Equation</u>
72 = 5x + 22
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 22 on both sides: 50 = 5x
- Divide 5 on both sides: 10 = x
- Rewrite: x = 10
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 72 = 5(10) + 22
- Multiply: 72 = 50 + 22
- Add: 72 = 72
Here we see that 72 does indeed equal 72.
∴ x = 10 is the solution to the equation.
Answer:10
Step-by-step explanation:
ok they are 18 apples
and they ate them
one ate two more thatn the other one
so we can say that one of them is x(charles)
and the one who ate two more is x+2(lisa)
so we get this
x+x+2=18
2x+2=18
2x+18-2
2x=16
x=8
so charles ate 8
and lisa 10(8+2)
The answer would be 93.887
