Question

Solve & Check

5x + 7 = 2x - 14

Answer 1

1) subtract \(2x\) from both sides
2) subtract 7 from both sides
3) divide both sides by 3

Answer 2

@satellite73 I got 3x = -7. so i divided & got x= 2 1/7. Now i"m confused on the check part

Answer 3

Now that you know the value of x (x=2 1/7), plug 2 1/7 for x back into the original equation 5x + 7 = 2x - 14. See if both side are equal to one another.

Answer 4

when you subtract \(7\) from both sides you should get \(3x=-21\) because \(-14-7=-21\)

Answer 5

lets work through the steps
\[5x + 7 = 2x - 14
\]
\[3x+7=-14\]
\[3x=-21\]
\[x=-\frac{21}{3}=-7\]

Answer 6

it is a common mistake to drop the minus sign when the term in front is gone,
but remember the right hand side had \(2x-14\) so when you subtract \(2x\) you goet \(-14\) not \(14\)
the minus sign comes with the number
