What does 10 minus y equals 2y plus 3 equal?
10-y=2y+3 10-3=2y+y 7=3y 7/3=y
How do you solve 3x plus 2y equals 4 4x plus 3y equals 7?
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
Is 3x plus 2y equals 7 and -4x-3y equals 10 dependent?
Yes and their solutions are x = 41 and y = -58
3y-7 plus y plus 27 equals 6y plus 20-4y?
3y - 7 + y + 27 = 6y + 20 - 4y Collect terms: 4y + 20 = 2y + 20 Subtract 20 4y = 2y The only way that can happen is if y = 0
What is the answer to 5y-7 equals 2y plus 11?
5y-7 = 2y+11 (+7 to both sides) 5y = 2y+18 (- 2y from both sides) 3y = 18 (divide both sides by 3 ) y = 6 y=6
5-2y equals -3y - 2?
5 - 2y = -3y - 2Subtract 5 from each side:-2y = -3y - 7Add 3y to each side:y = -7
What does 10 minus y equals 2y plus 3 equal?
10-y=2y+3 10-3=2y+y 7=3y 7/3=y
Is this a no solution 6x - 2y equals 4 -9 plus 3y equals 12?
(x, y) = (3, 7) is a solution.
How do you solve 3x plus 2y equals 4 4x plus 3y equals 7?
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
Is 3x plus 2y equals 7 and -4x-3y equals 10 dependent?
Yes and their solutions are x = 41 and y = -58
3y-7 plus y plus 27 equals 6y plus 20-4y?
3y - 7 + y + 27 = 6y + 20 - 4y Collect terms: 4y + 20 = 2y + 20 Subtract 20 4y = 2y The only way that can happen is if y = 0
Solve the following system of equations x plus 2y -6 equals z 3y-2z equals 7 4 plus 3x equals 2y -5z?
x+2y-6=z -z -z x+2y-z-6=0 +6 +6 ---------> x+2y-z=6 3y-2z=7 ---------> 0x+3y-2z=7 4+3x=2y-5z -3x -3x ---------> -3x+2y-5z=4 Put them into a matrix, for x,y,z and their answers. Solve for [A]-1[B], and the answer comes to: x= 1.75, y= 1.5, and z= -1.25
What is the answer to 5y-7 equals 2y plus 11?
5y-7 = 2y+11 (+7 to both sides) 5y = 2y+18 (- 2y from both sides) 3y = 18 (divide both sides by 3 ) y = 6 y=6
What does 14x-2y plus 7x-3y plus -3x equal to?
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
What type of system is 3x plus 2y equals 7 and -4x-3y equals 10?
They are simultaneous equations and their solutions are x = 41 and y = -58
The addition method for x plus y equals 8 and -x plus 2y equals 7?
Add the two equations: x + y - x + 2y = 8 + 7 ie 3y = 15 so y = 5 making x = 3.
What is 5x - 3y -7x plus 2y plus 3x?
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
