Answer 1

Respuesta:

2.

$4 + 3x = 13 \\ 3x = 13 - 4 \\ x = \frac{9}{3} \\ x = 3$

3.

$15x - 3 = 12 \\ 15x = 12 + 3 \\ x = \frac{15}{15 } \\ x = 1$

4.

$5x + 3 = 10 \\ 5x = 10 - 3 \\ x = \frac{7}{5}$

5.

$2t - 4 = 5 - t \\ 2t + t = 5 + 4 \\ 3t = 9 \\ t = 9 \div 3 \\ t = 3$

6.

$4x - 12 = 15 - 2x \\ 4x + 2x = 15 + 12 \\ 6x = 27 \\ x = \frac{27}{6} \\ x = 4 \frac{1}{2}$

7.

$\frac{5}{2} x - 4 = 7 \\ \frac{5}{2} x = 7 + 4 \\ 5x = 11(2) \\ x = \frac{22}{5} \\ x = 4.4$
