Solve the literal equation for x. Y= Mx + b

x = y - b

or, x = y - b/m

    m

Step-by-step explanation:

Given: y = mx+b

First, we need to isolate the variable we're solving the equation for.

To do that, we'll subtract b from both sides.

y = mx + b

-b         - b

y - b = mx

Then, to get x by itself we must divide the equation by m.

y - b = mx

      m

Now, we have:

x = y - b

or, x = y - b/m

    m

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

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
