Question

Can I have some help with this

Answer 1

$5x - 20 = 4x + 2$

X= a number making both expressions equivalent since the picture shows them being equal.

$5x - 20 = 4x + 2$

1st : We will move the terms.

Note: (anything moved to the other side of the equal sign will change signs)

$5x - 4x = 2 + 20$

2nd : Calculate,

$1x = 22$

1x = x

Meaning 1x and x are the same meaning,

$x = 22$

Now, we must calculate with x being 22...

$5 (22) - 20$

Solve by multiplying first then subtracting,

$110 - 20 = 90$

This means 5x - 20 = 90 and if the two expressions were equivalent then 4x + 2 should also equal 90 yet let's check...

$4(22) + 2$

Solve by multiplying first then subtracting,

$88 + 2 = 90$

$90 = 90$

So both expressions equal 90.

Finally, let's calculate 2x + 6 with 22 as x,

$2(22) + 6$

Solve by multiplying first then subtracting,

$44 + 6 = 50$
