Question

equacao do 1 grau com uma variável

b) 8+m=10
c)y+9=3
k) 6y+3=5y
n) 2(3y+1)=11
q) x-2(x-1)=4-3(x-2)

pls

Answer 1

b) m = 10-8 = 2
C)y = 3-9 = -6
d) 6y - 5y = -3
Y = -3
E) 6y +2 = 11
6y = 11-2 = 9
Y = 9/6
Y = 3/2

F) x -2x+2 = 4-3x+6
X-2x+3x = 4+6-2
2x = 8
X =4

Answer 2

b) 8+m=10
m=10-8
m=2

c) y+9=3
y=3-9
y= -6

K) 6y+3=5y
6y-5y= -3
y= -3

n) 2(3y+1)=11
6y+2=11
6y=11-2
6y=9
y=9/6. ou y=9/6=1,5

q) x-2(x-1)=4-3(x-2)
x-2x+2=4-3x+6
x-2x+3x=4+6-2
2x=8
x=8/2
x=4
