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 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
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.
