Question

guys!!! I need a help!!!fast
please say the answer
its maths lesson- linear equations in one variable ​

Answer 1

$\sf\huge\underline{Answer:}$

1) $x - 2 = 7$

$x = 9$

→

2) $15 = x - 7$

$x = 15 + 7 = 22$

$x = 22$

→

3) $\frac{t}{5} = 10$

$t = 50$

→

4) $\frac{x}{5} + 4 = \frac{3}{2}$

$\frac{x}{5} = \frac{3 - 8}{2}$

$x = \frac{ - 5 \times 5}{2} = \frac{ - 25}{2}$

→

5) $14y - 8 = 13$

$14y = 13 + 8$

$y = \frac{21}{14} = \frac{3}{2}$

→

6) $17 + 6p = 9$

$6p = 9 - 17$

$p = \frac{ - 4}{3}$

Have a good evening!

Answer 2

$1. \: x - 2 = 7$

$\: \: \: \: x = 7 + 2$

$\: \: \: \: x = 9$

$2. \: 15 = x - 7$

$\: \: \: \: 15 + 7= x$

$\: \: \: \: 22 = x$

$3. \: \frac{t}{5} = 10$

$\: \: \: \: \: t = 10 \times 5$

$\: \: \: \: \: t = 50$

$4. \: \frac{x}{5} + 4 = \frac{3}{2}$

$\: \: \: \: \frac{x}{5} = \frac{3}{2} - 4$

$\: \: \: \: \frac{x}{5} = \frac{3 - 8}{2}$

$\: \: \: \: \frac{x}{5} = \frac{ - 5}{2}$

$\: \: \: \: x = \frac{ - 5}{2} \times 5$

$\: \: \: \: x = \frac{ - 25}{2}$

$5. \: 14y - 8 = 13$

$\: \: \: \: 14y = 13 + 8$

$\: \: \: \: 14y = 21$

$\: \: \: \: y = \frac{21}{14}$

$6. \: 17 + 6p = 9$

$\: \: \: \: 6p = 9 - 17$

$\: \: \: \: 6p = - 8$

$\: \: \: \: p = \frac{ - 8}{6}$
