4-2y = 2
What else can I help you with?
What is the y-intercept of the line with equation -4 plus 2y equals 24?
-4 + 2y = 242y + 4 = 242y + 4 - 4 = 24 - 42y + 4 - 4 = 24 - 42y = 24 - 42y = 202y/2 = 20/22y/2 = 20/2y = 20/2y = 10Therefore the y-intercept is at (0,10) or has a value of 10
Answer this equations x plus 42y equals 4?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
What is 6(4x-(2-5y plus 2x) plus 2y)?
To simplify the expression ( 6(4x - (2 - 5y + 2x) + 2y) ), first simplify inside the parentheses: ( 2 - 5y + 2x ) becomes ( 4x - 2 + 5y + 2y = 4x + 7y - 2 ). Thus, the expression simplifies to ( 6(4x - (4x + 7y - 2) + 2y) = 6(-7y + 2) = -42y + 12 ). Therefore, the final result is ( -42y + 12 ).
What is 2y plus 3 equals 4 as decimal or fraction?
2y + 3 = 42y = 4 - 32y = 1divide both sides of the equation by 22y/2 = 1/2y = 1/2 in fractionory = 0.50 in decimal
How do you rewrite -3x plus 2y equals -4?
-3x + 2y = -4There are lots of different ways to write it.Here are a few:-3x = -2y - 43x = 2y + 42y = 3x - 4-2y = -3x + 4x = 2y/3 + 4/3y = 3x/2 - 2

What is the y-intercept of the line with equation -4 plus 2y equals 24?
-4 + 2y = 242y + 4 = 242y + 4 - 4 = 24 - 42y + 4 - 4 = 24 - 42y = 24 - 42y = 202y/2 = 20/22y/2 = 20/2y = 20/2y = 10Therefore the y-intercept is at (0,10) or has a value of 10
How many solutions do these equations havey = 2x + 42y = 4x + 8?
Infinite number of solutions
Answer this equations x plus 42y equals 4?

What is 2y plus 3 equals 4 as decimal or fraction?
2y + 3 = 42y = 4 - 32y = 1divide both sides of the equation by 22y/2 = 1/2y = 1/2 in fractionory = 0.50 in decimal
X has 14 more than Y Together they have 56 How much money does each of tham have?
Let the amount that Eks has = X.Let the amount that Wye has = Y.X = Y + 14.X + Y = 56(Y + 14) + Y = 562Y + 14 = 562Y = 42Y = 21 ===> X = 35
How do you rewrite -3x plus 2y equals -4?
-3x + 2y = -4There are lots of different ways to write it.Here are a few:-3x = -2y - 43x = 2y + 42y = 3x - 4-2y = -3x + 4x = 2y/3 + 4/3y = 3x/2 - 2
How do you factor out the coefficient of a variable?
Coefficients are numbers. Find the GCF of the numbers and divide them by it.Example: 30x + 42yFind the GCF of 30 and 42.Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Select the common factors.2 x 3 = 6, the GCF30/6 = 542/6 = 730x + 42y = 6(5x + 7y)
Which two consecutive integers are such that the difference between four times the first and twice the second equals eighty-two?
We have x and y where 1. y - x = 1 2. 4x - 2y = 82 Solve simultaneously by eliminating y, to get 2x = 84 x = 42y = 43. ---- Arguably, a 'difference of 82' could also mean that 4x - 2y = -82 In this case, we get 2x = -80 x = -40, y = -39
How do you solve the system of equations -2x plus 6y equals 6 and -7x plus 8y equals -5?
Make the equations contain an equal co-efficient of x: first multiplied by 7 = -14x + 42y = 42 second multiplied by 2 = -14x + 16y = -10 Subtract leaving 26y = 52 y = 2 -2x + 12 = 6 -2x = -6 x = 3 Check these values in the two original equations.
What happens to the literal coefficient when you collect like terms?
Lets look at an example. In the expression 21x+42y x is a litteral coefficient of 21 and y is a literal coefficent of 42. We could write this as 21(x+2y) so we add the literal coefficients, well we add one of them to 2 times the other one. if you had 3x+5y, there is nothing you can really do to add these literal coefficients. How about a multiplication problem, 3xy(2xy)=6x^2y^2 so we multiply the literal coefficients. So the answer is it depends on the problems, sometimes we add the, sometimes we multiply them, sometimes we divide them and sometimes we can not do anything!
