Sagot :
the negative at the other side of the parenthesis must be distributed inside the parenthesis changing the equation to 16d -4 + 5d = -67.
now add any like terms. in this equation that would be 16d + 5d = 21d
now the equation vhanges too 21d - 4 = -67
now you isolate the variable. so add 4 to both sides of the equal sign
21d - 4 (+4) = -67 (+4)
21d = - 63
divide by 21 on both side of equal sign 21d(/21) = -63 (/21)
d= -3
