Question

A) X+5=8
B) 2x=18
C)x÷4=2 ?

Answer 1

■ Letra A:

$\sf \: x + 5 = 8 \\ \sf \: x = 8 - 5 \\ \sf \: x = 3$

■ Letra B:

$\sf \: 2x = 18 \\ \sf \: x = 18 \div 2 \\ \sf \: x = 9$

■ Letra C:

$\sf \: x \div 4 = 2 \\ \\ \sf \: \frac{1}{4} x = 2 \\ \\ \sf \: 4 \times \frac{1}{4} x = 4 \times 2 \\ \\ \sf \: 4 \times \frac{1}{4} x \div 4 = 4 \times 2 \\ \\ \sf \: x = 4 \times 2 \\ \\ \sf \: x = 8$
