ECUACIONES DE PRIMER GRADO "OMEGAS"
1) x+4= 28
x= 28-4 x= 24
2) y-6.5= 31
y= 31+6.5 y= 37.5
3) 8z=40+3z
8z-3z= 40
5z= 40
z= 40/5 z= 8
4) 10x= -5x+60
10x+5x= 60
x= 60/15 x= 4
5) -15y+3= -36-18y
-15y+18y= -36-3
3y= -39
y=-39/3 y= -13
6) 2x+4+ (3-4)= 3x+12
2x+4-3+4= 3x+12
2x-3x= 12-4+3-4
-1= 7 x= 7/1
7) 4(3x+2)-8= 5(2x+3)+5
12x+8-8= 10x+15+5
12x-10x= 15+5-8+8
2x= 20
x= 20/2 x= 10
8) 15x-40-5x-20= 0
15x-5x= 0+20+40
10x= 60
x=60/10 x= 6
9) 16-(-2x-4)-5x-3x+2= -4x-(-8x+2)
16+2x+4-5x-3x+2= -4x+8x-2
2x-5x-3x+4x-8x= -2-16-4-2
-10x= -24
x= -24/-10 x= 2.4
10) -(7x-2+12)+(-5x-3x+4)= -(-x+7)-(6x-4-7)
-7x+2-12+5x+3x-4= +x-7-6x+4+7
-7x+5x+3x-x+6x= -7+4+7-2+12+4
6x= 18
x= 18/6 x= 3
11) -18- [3(x+2)+4]= 21- [6(-2x-2)+1]
-18-3(x+2)+4= 21-6(-2x-2)+1
-18-3x-6+4= 21+12x+12+1
-3x-12x= 21+12+1+18+6-4
-15x=54
x= 54/-15 x= -3.6
