1. 5(x) - [4 + x] = ?
4(x - 1)
4 = ?
x - 1 = ?
Now let's add ( + ) to your sides
Answer: x = 1
2. [tex] \frac{2}{3} (x) - \frac{1}{2} [/tex] = ?
[tex] \frac{1}{2} [/tex]
[tex] \frac{2}{3} (x) - \frac{1}{2} [/tex] = ?
[tex] \frac{2}{3} [/tex]
L denominator = 3
R denominator = 2
Put them together it would be 6
[tex] \frac{4(x) - 3}{6 } [/tex] = ?
4(x) - 3 = ?
Let's add 3 from your sides
Repeat the process but let's divide by 4
4(x) = 3
Answer x = [tex] \frac{3}{4} [/tex]
3. 3(x) - 2(x) + 4 - [tex] \frac{15}{3} [/tex] = ?
[tex] \frac{5}{1} [/tex]
x + 4 - 5 = ?
x - 1 = 0
Now, let add the number 1 from each sides
Answer: x = 1
4. 4(x) + 7 - 2(x) + 17 = ?
2(x - 5)
2 = ?
x - 5 = 0
Replace the subtraction symbol and make it a addition symbol ( but by 5)
Answer: x = 5
5. .5(x) - 10 = ?
[tex] \frac{1}{2} [/tex]
[tex] \frac{1}{2} (x) - 10[/tex] = ?
[tex] \frac{10(2) }{2} [/tex]
[tex] \frac{x - 20}{2} [/tex]
x - 20 = 0
Add the number 20 to each of your sides after replacing the subtraction symbol to a addition symbol
Answer: x = 20
