Question

x/3+5=7 by trial and error method

Answer 1

Step-by-step explanation:

$\frac{x}{3} + 5 = 7 \\ x + 5 = 7 \times 3 \\ x = 21 - 5 = 16$

Answer 2

Answer:

x=56

Step-by-step explanation:

$\frac{x}{3 + 5 } = 7$

$\frac{x}{8} = 7$

$x = 7 \times 8$

$x = 56.$

Verification:

$\frac{x}{3 + 5} = 7$

$\frac{56}{8} = 7$

$7 = 7.$

So, x=56.
