Step 1: Multiply 4 by (5n-7). = 20n - 28
Step 2: Subtract 10n from both sides. The equation is now 10n - 28 = 2.
Step 3: Add 28 to both sides. The equation is now 10n = 30.
Step 4: Divide both sides by 10. The equation is now n = 3.
The final answer is n = 3.

First distribute the 4(5n-7);
20n-28=10n+2
Now subtract both sides by 10n and add 28 to both sides;
20n-10n=2+28
10n=30
n=3
Hope you understand
