Question

Given the equation 4x 7 = 3(2x − 5), solve for the variable. Explain each step and justify your process.

Answer 1

Start with multiplying 4*7 to get 28
The equation simplifies to 28=3(2x-5)
Next, multiply the three into (2x-5), leaving the equation as 28=6x-15
After that, add fifteen to 28, getting 42=6x
Next, divide 42 by 6, getting x=7
