give answer for more points pls need help ​

Answer 1

1. 3x-1=14

3x = 14+1 = 15

x = 15/3

x = 5

2.2y = 20

y=20/2

y = 10

3.10+2x=6

2x = 6-10

2x = -4

x = -4/2

x = -2

4. 2μ\5 = 8

2μ = 8*5 = 40

μ = 40/2

μ = 20

5.2x+5 = 14-x

x² = 14-5

x² = 9

x = 3

6. x/5+3 = 8

x/5 = 8-3 = 5

x = 5*5

x = 25

7.6x-3 = 15

6x = 15+3 = 18

x = 18/6

x = 3

8. 4m + 2/5 = 1

4m = 1-2/5 = 0.6

m = 0.6/4

m = 0.15

Answer 2

Answer:

i) x = 5

ii) y = 10

iii) x = 2

iv) z = 20

v) x = 3

vi) x = 25

vii) x = 3

viii) m = 4/3

Step-by-step explanation:

i)

$3x - 1= 14$

Add 1 to both sides of the equation.

$3x - 1 + 1 = 14 + 1$

$3x = 15$

$x = \frac{15}{3}$

$x = 5$

ii)

$2y = 20$

Divide both sides of the equation by 2

$\frac{2y}{2} = \frac{20}{2}$

$y = 10$

iii)

$10 - 2x = 6$

Subtract 10 from both sides of the equation

$10 -10 - 2x = 6 - 10$

$- 2x = - 4$

$- x = \frac{ -4}{2}$

$- x = - 2$

$x = 2$

iv)

$\frac{2z}{5} = 8$

Multiply both sides of the equation by 5

$\frac{2z}{5} \times 5 = 8 \times 5$

$2z = 40$

$z = \frac{40}{2 }$

$z = 20$

v)

$2x + 5 = 14 - x$

Subtract 5 from both sides

$2x + 5 - 5 = 14 - x - 5$

$2x = 14 - 5 - x$

$2x = 9 - x$

Move the right hand side x to left side of the equation

$2x + x = 9$

$3x = 9$

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

$x = 3$

vi)

$\frac{x}{5} + 3 = 8$

Subtract 3 from both sides

$\frac{x}{5} + 3 - 3 = 8 - 3$

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

Multiply both sides by 5

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

$x = 25$

vii)

$6x - 3 = 15$

Add 3 to both sides

$6x - 3 + 3 = 15 + 3$

$6x = 18$

$x = \frac{18}{6}$

$x = 3$

viii)

$4m + \frac{2}{5} = 1$

Multiply both sides by 5

$4m + \frac{2}{5} \times 5 = 1 \times 5$

$4m + 2 = 5$

Subtract 2 from both sides

$4 m + 2 - 2= 5 - 2$

$4m = 3$

$m = \frac{4}{3}$
