Question

X +2X-1-3=X

-3x+10=2x+8+1​

Answer 1

Explicação passo-a-passo:

X +2X-1-3=X

3x-4=x

3x-x=4

2x=4

x=4/2

x=2

=================

-3x+10=2x+8+1

-3x+10=2x+9

-3x-2x=9-10

-5x=-1

x=-1/-5

x=1/5

Answer 2

I) x + 2x - 1 - 3 = x

3x - x = +3 + 1

2x = 4

x = 4/2

x = 2

II) -3x + 10 = 2x + 8 + 1

-3x - 2x = 9 - 10

-5x = -1

x = -1/-5

x = 1/5
