Question

Given: 3x + 1 = 2 + 2x – 4

Prove: x = –3

Answer 1

Given the equation 3x + 1 = 2 + 2x – 4, use the commutative property to rearrange the terms so that like terms are next to one another. This gives the equation 3x + 1 = 2 – 4 + 2x. Then use the associative property of addition to group the like terms. This gives the equation 3x + 1 = (2 – 4) + 2x. Next, combine like terms to get the equation 3x + 1 = – 2 + 2x. Use the subtraction property of equality to subtract 2x from both sides of the equation. This gives the equation x + 1 = – 2. Then use the _________________________ to subtract 1 from both sid

Answer 2

This gives the solution x = –3. Therefore, given the equation 3x + 1 = 2 + 2x – 4, x is equal to –3.

Which justification was left out of the paragraph proof above?

Answer 3

SOMEONE HELP MEEEEEE

Answer 4

rearrange the equation..... 3x-2x=2-4-1= -3...proved....

Answer 5

so what would my answer be ?

Answer 6

it would be X=-3

Answer 7

how would i write that out ?

Answer 8

well can you solve this 3x-2x= ?

Answer 9

\[3x-2x= 2-4-1\]
next step would be \[x=-3 \] that's it...you're done
