2x + 8y=5 solve for x
lora16 [44]

Answer:

x=\frac{5-8y}{2}

Step-by-step explanation:

1 Equation is given, so solving for "x" would mean an expression for "x", where

x = SOMETHING

First, we need to isolate x, so we need to take "8y" to the other side, we have:

2x+8y=5\\2x=5-8y

Now, since we don't have "x" isolated yet, we need to take out the 2, so we will divide both sides by 2 to get x isolated. Shown below:

2x=5-8y\\x=\frac{5-8y}{2}

So, x has this expression  x=\frac{5-8y}{2}

<h3>What is Linear Equation?</h3>

A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line.

Here, The solution to this Linear System is already shown by the graph. This is also called the Graph Method. The Solution of this Linear System is this common point in this case, (0,2).

Since each equation is represented by a line. So We have  g(x) for the red line, and f(x) for the blue one. Each line is a set of points, We know that from the Euclidean Geometry and its common point (0,2) solves this system.

Thus, the correct answer is option c i.e. (0, 2)

Can somebody help meh? reeeeeeeeee
Juli2301 [7.4K]

Answer:

A. 200 miles/hour

Step-by-step explanation:

600 divided by 3, since division is the opposite of multiplication we can multiply:

3 X 150 = 450

3 X 50   = 150

we can add 150 and 50 together to get 200 and that's your answer

What is 23×4+9-4÷6×1536=?
mart [117]

Use Bedmas for this question

Follow the order in which comes first left to right. For addition and subtraction, do whichever comes first. For division and multiplication do which ever comes first.

B=Bedmas

E=Exponents

D=Division

M=Multiplication

A=Addition

S=Subtraction

1.

23*4=92

4*6=4/6

4/6=2/3

2.

2/3*1536=2.512/1

3.

92+9=101

4.

-1024+101=-923

So the final answer is -923


Hope it helps :)


-923
