Since you say you are looking for the sum, I will assume that the equation that you should have written is 3z + 2 + z = 5.
3z + 2 + z = 5
3z - 2 + z = 5 -2
3z + z = 3
4z = 3
4z/4 = 3/4
z = 3/4

If 3z/2 = 9 then the value of z is 6
Add like terms to like: (2z - 20) + (3z + 5) = (2z + 3z) + (-20 + 5) = 5z - 15 2z is shorthand for z+z, 3z is shorthand for z+z+z, so: 2z + 3z = (z+z) + (z+z+z) = z+z+z+z+z = 5z Or, to put it another way, just add the coefficients: 2z + 3z = (2+3)z = 5z.
3z+2= x ; z=53(5)+215+217Blake watson 63877
The sum of the digits in 252 is 2 + 5 + 2 which equals 9.
change the equation around 4x-6=2 becomes 4x=2+6
