It is the same as: 11z = 132 Divide both sides by 11: z = 12
It is an expression in two variables, z and t. It can be simplified to 14z + 2t or 2*(7z + t)
17z + 34 = 6z + 5 17z - 6z + 34 = 6z - 6z + 5 11z + 34 = 5 11z + 34 - 34 = 5 - 34 11z = -29 11z/11 = -29/11 z = -2 7/11 or -29/11 Double check your answer: 17z + 34 = 6z + 5 17(-2 7/11) + 34 = 6z + 5 -44 9/11 + 34 = 6z + 5 -10 9/11 = 6z + 5 -10 9/11 = 6(-2 7/11) + 5 -10 9/11 = -15 9/11 + 5 -10 9/11 = -10 9/11 17z + 34 = 6z + 5 when Z = -2 7/11
Mathematics"mathematics" is a plural noun already, the subject is Mathematics!
Choose w = 0 or 1 or 2, and x, y, z = 0 or 1 each. Then any number of the form 2w*5x*7y*11z will go into the given number.
