Question

What is 4x + 3 = 2x +7

Answer 1

Answer: $x=2$

Step-by-step explanation:

First, subtract by 3 from both sides.

$4x+3-3=2x+7-3$

Then, simplify.

$4x=2x+4$

Next, subtract by 2x from both sides.

$4x-2x=2x+4-2x$

Simplify.

$2x=4$

Divide by 2 from both sides.

$\frac{2x}{2}=\frac{4}{2}$

Finally, simplify.

$x=2$

Hope this helps!

Answer 2

Bring like terms together
(REMEMBER CHANGE THE SIGN WHEN MOVING ACROSS THE EQUAL SIGN i.e. - becomes + and + becomes -)
4x - 2x = 7 - 3
2x = 4
divide both sides by 2
x = 2
