Consider this equation:
-2x - 4 + 5x =8
Generate a plan that will be used to solve for the variable. Describe the steps that will be used.

x=4

Step-by-step explanation:

The first thing you need to do is combine like terms which would give you

3x-4=8 then you would add four to both sides giving you 3x=12 finally you would divide both sides by 3 giving you x=4.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

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
