Question

4(2x - 5) = 5x -20 +3x

Answer 1

All real numbers

Explanation:

Distribute the 4 on the left side

4(2x-5)=5x-20+3x

8x-20=5x-20+3x

Combine like terms on the right side

8x-20=8x-20

All real numbers are solutions, because both sides are equal

Hope this helps! :)

Answer 2

Firstly, you have yo multiply out the first bracket by multiplying (2x - 5) by 4. The equation would then look like:

8x - 20 = 5x - 20 + 3x

Then you have to put normal numbers on one side and x-terms on the other. It would look like:

-20 + 20 = 5x + 3x - 8x

Then you should solve the additions and subtractions

0 = 0x

Since ANY number multiplied by 0 is zero, your equation has infinite solutions.
