What is the answer to. 4 (5n-7) = 10n+2

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
