Answer 1

a)

$x - 5(2x - 3) = 3(x - 1) + 4$

$x - 10x + 15 = 3x - 3 + 4$

$15 - 1 = 3x + 9x$

$12x = 14$

$x = 7 \6$

b)

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

$\frac{2x - 10 + 12}{3} = 5x - 2$

$2x + 2 = 15x - 6$

$2 + 6 = 15x - 2x$

$x = 8 \13$

c)

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

$\frac{15 - x - 2}{5} = 15x - 10$

$13 - x = 75x - 50$

$13 + 50 = 75x + x$

$x =63 \76$

d)

$3(x - 4) + 10 = 13 - x$

$3x - 12 +10 = 13 - x$

$3x + x = 13 + 2$

$4x = 15$

$x = 15 \4$
