What is the answer for 7-2x=3

x = 2

Step-by-step explanation: To solve for x in this problem, the first thing we want to do is subtract 7 from both sides of the equation in order to get our x term by itself.

On the left side, 7 - 7 cancels and here's the tricky part. An extremely common mistake would be to forget to bring down the negative leaving yourself with 2x on the left side.

Be very aware of this mistake so it doesn't claim you as a victim. On the right side of the equation, 3 - 7 is -4.

So we have -2x = -4.

Now divide both sides by -2 so x = 2.

answer: can and shows the work

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
