Question

Solve:
a. 5y – 3 = – 18
b. -3x – 9 = 0
c. 4 + 3(z - 8) = -23
d. 1 – 2(y – 4) = 5

Answer 1

Step-by-step explanation:

a). -3 is the answer of this question

Answer 2

$1) \: \: 5y - 3 = - 18$

$5y = - 18 + 3$

$5y = - 15$

$y = \frac{ - 15}{5}$

$y = - 3$

$2) \: - 3x - 9 = 0$

$- 3x = 9$

$x = \frac{9}{ - 3}$

$x = - 3$

$3) \: 4 + 3(z - 8) = -23$

$4 + 3z - 24 = - 23$

$3z = - 23 + 20$

$3z = - 3$

$z = \frac{ - 3}{3}$

$z = - 1$

$4)1 – 2(y – 4) = 5$

$1 - 2y + 8 = 5$

$9 - 2y = 5$

$9 - 5 = 2y$

$4 = 2y$

$y = \frac{2}{4}$

$y = \frac{1}{2}$
