I need help I’m in grade 10 and confused

from what i can see, i cant see anything i try to enlarge it but still doesnt work sorry i couldnt help

Step-by-step explanation:

3. d) x = 6

e) - 3/2

f) x = - 4

g) y = 4

h) x = 7

3. a = 3/4

4. x = - 2

Step-by-step explanation:

3. d) 2x - 5 = 7

2x = 7 + 5

x = 12/2

x = 6

e) 7 - 2n = 10

- 2n = 10 -7

- 2n = 3

n = 3/- 2 = - 3/2

f) 2x - 3 = 5x + 9

-3 - 9 = 5x - 2x

-12 = 3x

- 12/3 = x

x = - 4

g) 4(y-3)= 2y - 4

4y - 12 = 2y - 4

4y - 2y = -4 + 12

2y = 8

y = 8/2

y = 4

h) x^2 - 11 = 38

x^2 = 38+11

x^2 = 49

x = sqrt 49

x = 7

3.

a/3 - 5/12 = - 1/6 (common denominator: 12)

4a/12 - 5/12 = -2/12

(4a - 5)12 = -2/12 (12/12=1)

4a - 5 = -2

4a = - 2 + 5

4a = 3

a = 3/4

4.

(2x+1)/3 = (x-6)/8

8(2x+1) = 3(x-6)

16x + 8 = 3x - 18

16x - 3x = - 18 - 8

13x = - 26

x = - 26/13

x = - 2

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
