Question

solve 3(z+2)=15 so that the answer should be -1​

Answer 1

Here is your answer ↓

3(z + 2) = 15

» z + 2 = 15/3

» z + 2 = 5

» z = 5 - 2

» z = 3

Answer 2

Step-by-step explanation:

$3(z + 2) = 15 \\ \\ 3 \times z = 3 \\ 3 \times 2 = 6 \\ \\ 3z + 2 =15 \\ \\ 3z = 15 -2$

$3z = 15 - 2 \\ \\ 3z = 13 \\ \\ z = 13 \div 3 \\ \\ 4.3333333333$
