Question

Hola una pregunta alguien me hace el favor de resolverme estos ejercicios de ecuaciones
x+9-12=-22
x-18+45=36
x-12+43-71=100
x-18+23+x=-14
x-146+38=209
x-207+400=500

Answer 1

x+9-12=-22
x-3 =-22
x= -22+3
x = -19

x-18+45=36
x + 27 = 36
x = 36-27
x = 9

x-12+43-71=100
x + 31 -71 = 100
x - 40 = 100
x = 100 + 40
x = 140

x-18+23+x=-14
2x + 5 = -14
2x = -14-5
2x = -19
x = -19/2

x-146+38=209
x- 108 = 209
x = 209 + 108
x = 317

x-207+400=500
x + 193 = 500
x = 500- 193
x = 307
