Question

hi help i need your questions step by step answer ok ​

Answer 1

Answer:

a) y = 8

b) t = - 18/5

c) a = - 5

d) q = - 8

e) x = -2

Step-by-step explanation:

There are so many questions that's why I solving only the few one.

Point to be noted

i) If we change the place of any no. or variable between the equal sign the sign of the no. will change.

ii) Arrange the no. in one side and variable in one side.

iii) Just simplfy according to BODMAS rule.

Solution:

a)

$2y + \frac{5}{2} = \frac{37}{2} \\ \\ 2y = \frac{37}{2} - \frac{5}{2} \\ \\ 2y = \frac{37 - 5}{2} \\ \\ y = \frac{32}{2 \times 2} \\ \\ y = 8$

b)

$5t + 28 = 10 \\ \\ 5t = 10 - 28 \\ \\ 5t = - 18 \\ \\ t = - \frac{18}{5}$

c)

$\frac{a}{5} + 3 = 2 \\ \\ \frac{a}{5} = 2 - 3 \\ \\ \frac{a}{5} = - 1 \\ \\ a = - 5$

d)

$\frac{ q}{4} + 7 = 5 \\ \\ \frac{q}{4} = 5 - 7 \\ \\ \frac{q}{4} = - 2 \\ \\ q = - 2 \times 4 \\ \\ q = - 8$

e)

$\frac{5}{2} x = - 5 \\ \\ \frac{ \cancel{5}}{2} x = - \cancel{5} \\ \\ \frac{ x}{2} = - 1 \\ \\ x = - 1 \times 2 \\ \\ x = - 2$

I hope you will understand my answer.
