Answer:
-4
Step-by-step explanation:
53 = -19z+5+7z
53 = -12z+5 | -5 (on both sides)
48 = -12z | :(-12)
z = -4
Answer:
z=-4
Step-by-step explanation:
[tex]53=-19z+5+7z[/tex]
To solve for z, we need to get z alone
First we combine like terms
-19z +7z is -12z
[tex]53=-19z+5+7z[/tex]
[tex]53=-12z+5[/tex]
Subtract 5 from both sides in order to eliminate 5
[tex]48=-12z[/tex]
Divide both sides by -12 in order to eliminate -12
z= -4
The value of z is -4
