Question

Solve the following equations:
i) x+2/2 =13
ii) 16a -3 = -5
iii) y/10 -12 = 8
iv) -p = 2+p
v) 4x = -2x + 30

Answer 1

Answer:

4x = -2x + 30 is the correct answer

Answer 2

Step-by-step explanation:

Solution :

$(1) \: \: \: \frac{x + 2}{2} = 13$

$= > x + 2 = 13 \times 2$

$= > x + 2 = 26$

$= > x = 26 - 2$

$= > x = 24.$

$(2) \: \: \: 16a - 3 = - 5$

$= > 16a = - 5 + 3$

$= > 16a = - 2$

$= > a = \frac{ - 2}{16}$

$= > a = \frac{ - 1}{8} .$

$(3) \: \: \: \frac{y}{10 - 12} = 8$

$= > \frac{y}{ - 2} = 8$

$= > y = 8 \times - 2$

$= > y = - 16$.

$(4) \: \: \: \: - p = 2 + p$

$= > - p - p = 2$

$= > - 2p = 2$

$= > p = \frac{2}{ - 2}$

$= > p = - 1.$

$(5) \: \: \: \: 4x = - 2x + 30$

$= > 4x + 2x = 30$

$= > 6x = 30$

$= > x = \frac{30}{6}$

$= > x = 5.$
