What is the most efficient first step to isolate the variable term on one side of this equation? -9x = -4x + 5 A. Subtract 5 fro
2 answers:
For this case we have the following equation:
We want to clear x:
For this we must follow a series of steps, the first consists of adding 4x to both sides of the equation to obtain:
In this way, the variable term remains on one side of the equation.
Thus, the first step will be:
Add 4x to both sides

if we look on one side, we already have one measurement. 4 cm. ok, that's the measurement on that side. look to the left now. that other side is also the same length, so we take that number and multiply it be 2 to get
Wait! we're not done yet. look at the top. do you see the 3? well that's the width for the top of the rectangle. the bottom must be the same to right? so we get
add both equations and you get
The answer is 14cm! Don't forget to label. ;)
Answer:
- 0.8
Step-by-step explanation:
The first thing we want to do here is simplify the expression -
( 2x + 5 ) - 2x, Distribute the "
" to elements within the parenthesis
=
2x +
5 - 2x, Focus on simplifying the expression "
2x +
5 "
= - 2x
= - 2x, Combine fractions
= + 3
= x + 3
So we have our simplified expression " x + 3, " with
being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,
- 4 / 5 = - 0.8,
Solution = - 0.8
