79 + k = 84
84 - 79 = k
k = 5
77
7x + 8 = 84 7x = 84 - 8 x = 76/7 x = 10.8571
19
n= -2
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
p is obviously zero because any number x plus 0 equals itself.
x=7
v = -6
7
9y subtract 11 equals 7
It does not help you.
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
