sorry & answer of no-12 is -8/5

Answer 2

Answer:

$\huge{\underline{\mathtt{\red{(❥A}\pink{n}\green{s}\blue{w}\purple{e}\orange{r}\blue{a}\red{ll}}}}$

solution6)

$2x - 3 = 7 \\ 2x = 7 + 3 \\ 2x = 10 \\ x = \frac{10}{2 } \\ x = 5$

solution 7)linear equation

$ax + b - c = 0$

so, option a is correct answer

solution 8)

$3x = 2x + 18 \\ 3x - 2x = 18 \\ x = 18$

solution 9)

$\frac{t}{5} = 10 \\ t = 10 \times 5 \\ t = 50$

hence value of 't' is 50

solution 10)

$6x = 12 \\ x = \frac{12}{6 } \\ x = 2$

hence x = 2

solution 12)

$\frac{x }{3} + 1 = \frac{7}{15} \\ \frac{x + 3}{3} = \frac{7}{15} \\ x + 3 = 3 \times \frac{7}{15} \\ x + 3 = \frac{7}{5} \\ x = \frac{7}{5} - 3 \\ x = \frac{7 - 15}{5}$

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