Value of x = 19
(8x - 20) = (5x + 37)
3x = 57
x = 19
X=10 and X=3/4 basically it’s whatever X equals to make the inside the parentheses equal zero. So if I were to plug 10 into the first parentheses you’d have 10-10 which equals zero. Also the zero has to the the opposite sign of what’s in the parentheses. So if -10 is in the parentheses then the zero has to be the opposite so positive 10.
