Question

A)-3X+10=2X+8+1
B)5X-5+X=-7X+8-3X
C)-X-5+4X=-7X+8-3X
D)X+2X-1-3=X

Answer 1

a)
$- 3x + 10 = 2x + 9 \\ - 3x - 2x = 9 - 10 \\ - 5x = - 1 \\ x = \frac{1}{5}$
b)
$6x - 5 = - 10x + 8 \\ 6x + 10x = 8 + 5 \\ 16x = 13 \\ x = \frac{13}{16}$
c)
$3x - 5 = - 10x + 8 \\ 3x + 10x = 8 + 5 \\ 13x = 13 \\ x = 1$
d)
$2x - 1 - 3 = 0 \\ 2x - 4 = 0 \\ 2x = 4 \\ x = 2$
espero ter ajudado

Answer 2

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

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

-5x = -1

x = 1/5

b) 5x - 5 + x = -7x + 8 - 3x

5x + x + 7x + 3x = 8 + 5

16x = 13

x = 13/16

c) -x - 5 + 4x = -7x + 8 - 3x

-x + 4x + -7x + 3x = 8 + 5

13x = 13

x = 13 / 13

x = 1

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

x + 2x - x = 1 + 3

2x = 4

x = 4 / 2

x = 2
