Question

a. 6z = −18 b. 7x = 35 c. x 4 = 5 d. 2x + 15 = 25 e. 3x − 12 = 6 f. 2(y + 5) = 50 g. 4y − 42 = −22 h. 25x = −125

Answer 1

Explicación paso a paso:

$a)6z = - 18$

$z = - 18 \div 6$

$z = - 3$

$b)7x = 35$

$x = 35 \div 7$

$x = 5$

$c) x4 = 5$

$4x = 5$

$x = \frac{5}{4}$

$d)2x + 15 = 25$

$2x = 25 - 15$

$2x = 10$

$x = 10 \div 2$

$x = 5$

$f)2(y + 5) = 50$

$y + 5 = 25$

$y = 25 - 5$

$y = 25 - 5$

$e)3x - 12 = 6$

$3x = 6 + 12$

$3x = 18$

$x = 18 \div 3$

$x = 6$

$g)4y - 42 = - 22$

$4y = - 22 + 42$

$4y = 20$

$y = 20 \div 4$

$y = 5$

$h)25x = - 125$

$x = - 125 \div 25$

$x = - 5$
