Answer:
2z+6 or 2(z+3) are the equivalent expressions
Step-by-step explanation:
z+(z+6)

=2(z+3)
i hope this will help you :)
X = 4y
3x - y = 70
substitute the x in the second equation with the other half of the first equation.
3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11
now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating
done
