Question

3z-8=7...
solve this equation....​

Answer 1

$\huge\fbox\pink{Answer}$

$3z - 8 = 7$

$3z = 7 + 8$

$3z = 15$

$z = 15 \div 3$

$z = 5$

So, your answer is 5.........

Answer 2

3z - 8 = 7

∴ 3z = 7 + 8

∴ 3z = 15

∴ z = 15/3

∴ z = 5

So, the value of z is 5.

=> Verification :-

3z - 8 = 7

∴ 3(5) - 8 = 7

∴ 15 - 8 = 7

∴ 7 = 7

∴ RHS = LHS

Hence, the above answer is correct.
