Step-by-step explanation:
<u>Step 1: Define</u>
6(x - 1) = 9(x - 4)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 6x - 6 = 9x - 36
- Subtract 6x on both sides: -6 = 3x - 36
- Isolate <em>x</em> term: 30 = 3x
- Isolate <em>x</em>: 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>: 6(10 - 1) = 9(10 - 4)
- Subtract: 6(9) = 9(6)
Here we see that the 2 expressions are exactly the same.
∴ x = 10 is the solution to the equation.
Answer:

Step-by-step explanation:

4 |x = 5| = 20
First, divide both sides by 4. / Your problem should look like:
Second, simplify

to 5. / Your problem should look like:
Third, break the problem into 2 equations. / x + 5 = 5 and -(x + 5) = 5
Fourth, solve x + 5 = 5. /
Cancel 5 on both sides. /
Fifth, solve -(x + 5) = 5 /
Simplify brackets /

Add 5 to both sides /

Add 5 + 5 /

Multiply both sides by -1 /

x = -10
Sixth, collect the solutions to the problems. / Your problem should look like:

Answer:
x = -10, 0
