Solve the following equation. show your work.3/4x-20=7

3/4x - 20 = 7

3x/4 - 20 = 7   Common denominator is 4.

4 (3x/4 - 20) = 4 x 7  Distribute the 4 though the parenthesis

4 x 3x/4 - 4 x 30 = 4 x 7

3x - 4 x 20 = 4 x 7

3x - 80 = 4 x 7  

3x - 80 = 28  Add 80

3x = 28 + 80

3x = 108  Divide by 3

x = 108/3

x = 36

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

can you rephrase the question ? it is unclear : -)
