Answer 1

$a)x + 4 = 5 \\ x = 5 - 4 \\ x = 1$

$c)7 + x = 10 \\ x = 10 - 7 \\ x = 3$

$d)7 - x = 5 \\ 7 - 5 = x \\ 2 = x$

$f)2 = x - 9 \\ 2 + 9 = x \\ 11 = x$

$g)5 = 2 + x \\ 5 - 2 = x \\ 3 = x$

$i)2 - x = 9\\ 2 - 9 = x \\ - 7 = x$

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

$3x = 10 - 7 \\ 3x = 3 \\ x = 1$

$c)x - 9x = 9 - 7 \\ - 8x = 2 \\ x = - \frac{2}{8} \\ x = - \frac{1}{4}$

$x = 3 - 5 \\ x = - 2$

$e)6 = 12x - 2x \\ 6 = 10x \\ \frac{6}{10} = x \\ \frac{3}{5} = x$

$8 = x + 2x \\ 8 = 3x \\ \frac{8}{3} = x$

$g)5x - 13x = 6 - 10 \\ - 8x = - 4 \\ x = \frac{ - 4}{ - 8} \\ x = \frac{1}{2}$
