Question

Halla el valor de x en cada igualdad, aplicando la regla de la suma y del producto.
43x-29=-12
7x-11=17
9x+17=-118
102+18x=264
23x+15x=224+346
37x-235=-246

Answer 1

43x-29=-12

43x = -12 + 29

43x = 17

x = 17/43

x = 0.3953 

7x-11=17

7x = 17+11

7x = 28

X = 28/7

X = 4

9x+17=-118

9x = -118 – 17

9x = -135

x = -135/9

x = -15

102 + 18x = 264

18x = 264 -102

18x = 162

x = 162/18

x = 9


23x + 15x = 224 + 346
38x = 570
x = 570/38
x = 15

37x - 235 = -246
37x = -246 + 235
37x = -11
x = -11/37
x = -0.2972

Answer 2

• 43x-29 = -12
43x = -12 +29
43x = +17
x = 17/43.

R = 17/43.

• 7x-11 = 17
7x = 17+11
7x = 28
x = 28/7
x = 4.

R = 4.

• 9x+17 = -118
9x = -118-17
9x = -135
x = -135/9
x = -15.

R = -15.

• 102+18x = 264
18x = 264-102
18x = 162
x = 162/18
x = 9.

R = 9.

• 23x+15x = 224+346
38x = 570
x = 570/38
x = 15.

R = 15.

• 37x-235 = -246
37x = -246 +235
37x = -11
x = -11/37

R = -11/37.

Suerte eso es todo :)
