The expression written in the question is the rational expression.
(3z + 5)(z -7)
3z-5
It is an algebraic expression that can be simplified to: 16z+11
-47 + 6z = 3z-2-3z -3z-47 + 3z = -2+47 +473z = 45/3 /3z = 15

help me .. .
(3z + 5)(z -7)
3z-5
It is an algebraic expression that can be simplified to: 16z+11
-47 + 6z = 3z-2-3z -3z-47 + 3z = -2+47 +473z = 45/3 /3z = 15
15 = 3z - 6 15 + 6 = 3z 3z = 21 z = 7
An algebra expression is 2 or more terms which does not contain an equality sign as for example 2x+y-3z
Collect all the letters on one side and the numbers on the other; what you do to one side of the equals you do to the other: 3z + 2 = 6z - 13 → 3z +2 - 3z = 6z - 13 - 3z → 2 = 3z - 13 → 2 + 13 = 3z - 13 + 13 → 15 = 3z → 3z = 15 (this is just changing the equals around so that the letter is on the left) → 3z ÷ 3 = 15 ÷ 5 → z = 5
33z - 4 - 20z - 5 simplified would be 13z - 1.
Since 9z is a multiple of 3z, it is automatically the LCM.
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
