Question

A) 8A=56 B) 2=X:900 C) 7a + 7 = 56

Answer 1

Explicación paso a paso:

$1) \: 8a = 56 \\ a = 7 \\ 2) \: 2 = x \div 900 \\ x = 1800 \\ 3) \: 7a + 7 = 56 \\ 7a = 49 \\ a = 7$

Answer 2

8A = 56

A = 56/8

A = 7

2 = X/900

2(900) = X

1800 = X

7a + 7 = 56

7a =  56 - 7

7a = 49

a = 49/7

a = 7
