Answer:

(13)

x= 8

y=11

(14)

x= 20

y=20.75

(15)

x=9

y=13

Step-by-step explanation:

(13) 8x-1 = 11x -25

24=3x

x= 8

8(8)-1 +15y-48= 180

15y=165

y=11

(14) 7x-44 + 4x + 4= 180

11x= 220

x= 20

4(20)+4+39= 8y-43

123=8y-43

166=8y

y=20.75

(15) 12x+1=15x-26

3x=27

x=9

28+15(9)-26+4y-9=180

4y=52

y=13

Answer:

(8.21, -20.79)

Step-by-step explanation:

Given the simultaneous equation;

$\frac{a}{b} - \frac{b}{2} = 10\\a - b = 29$

From 2;

a = 29 + b ....3

Substitute 3 into 1;

$\frac{29+b}{b} - \frac{b}{2} = 10\\\frac{2(29+b)-b^2}{2b} = 10\\\frac{58+2b-b^2}{2b} = 10\\58+2b-b^2 = 20b\\b^2-2b-58 = -20b\\b^2-2b+20b -58 = 0\\b^2+18b-58 = 0\\$

Factorize

b = -18±√18²-4(-58)/2

b = -18±√324+232/2

b = -18±√556/2

b = -18±23.58/2

b = -18-23.58/2 and -18+23.58/2

b = -41.58/2 and 5.58/2

b = -20.79 and 2.79

Since a = 29 + b

when b = -20.79

a = 29 - 20.79

a = 8.21

Hence the solution to the system of equation is (8.21, -20.79)
