Of the following options, what could be a possible first step in solving te equation 3x-1=2x+4?

Note that in this equation, you are solving for x.

The first step i would take is "isolating the x". To do so, add 1 to both sides, and subtract 2x from both sides

3x (-2x) - 1 (+1) = 2x (-2x) + 4 (+1)

3x - 2x = 4 + 1

x = 5

hope this helps

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
