Question

Please answer the underlined questions from class 7 simple equations

Answer 1

ANSWER:

$8x = 24$

$x = \frac{24}{8}$

$x = 3$

________________________________________________________________________________________________

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

$x = 3 \times 7$

$x = 21$

________________________________________________________________________________________________

$\frac{3}{4}x = 12$

$3x = 12 \times 4$

$3x = 48$

$x = \frac{48}{3}$

$x = 16$

________________________________________________________________________________________________

$x - 11 = 9$

$x = 9 + 11$

$x = 20$

________________________________________________________________________________________________

$3x = 15$

$x = \frac{15}{3}$

$x = 5$________________________________________________________________________________________________

$\frac{x}{11} = 3$

$x = 3 \times 11$

$x = 33$

________________________________________________________________________________________________

$\frac{1}{4}x = \frac{9}{8}$

$x = \frac{9}{8} \times 4$

$x = \frac{9}{2}$________________________________________________________________________________________________

$11 - x = 2$

$- x = 2 - 11$

$- x = - 9$

$x = 9$________________________________________________________________________________________________

$\frac{16}{x} = 8$

$16 =8 \times x$

$16 = 8x$

$\frac{16}{8} = x$

$2 = x$

$x = 2$
