Question

resolva a equação :
a)3x-7=2x+6
B)x+19=40-2x
c)4x+7-x=11
d)9x-3=5x-18
e)10x+1=x+16-2x

Answer 1

a)3x-7=2x+6
3x-2x=6+7
1x=13
x=13
b)x+2x=40-19
3x=21
x=21/3
x=7
c)4x-x=11-7
3x=4
x=3/4
d)9x-5x=-18+3
4x=-15
x=-15/4
e)10x-x-16+2x=1
9x-14x=1
-5x=1
x=1/-5
(espero ter ajudado✌:)

Answer 2

a)3x-7=2x+6 = 3x - 2x = 6+7 ==. x = 13

B)x+19=40-2x ==> x+2x = 40-19 ==> 3x=39 ==> x = 13

c)4x+7-x=11 ==> 4x -x = 11+7 ==> 3x = 18 ==> x = 6

d)9x-3=5x-18 ==> 9x-5x = - 18 + 3 ==> 4x = - 15 ==. x = - 15/4

e)10x+1=x+16-2x ==> 10x- x+2x = 16 - 1 ==> 11x = 15 ==> x = 15/11
