7=2z+6
Please explain the answer too.

z = 1/2

Step-by-step explanation: subtract 6 from both sides to get  2z=1 divide both sides by 2, you get z = 1/2 check by inputting 1/2 for z

2(1/2)+6= 7

1/2 of 2 is 1

1+6=7

it checks out :)

z= 1/2

explanation:

if 7=2z+6, z would be 1/2, because 2 times 1/2=1. then 6+1 s equal to 7

f(x)= 19

Step-by-step explanation:

f(x)= -3x+4

f(x)= -3(-5)+4

f(x)= 15+4

f(x)= 19

Hope this helps :)
