2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
What is 2x plus 4y-5x plus 3y?
2x + 4y - 5x + 3y = 7y - 3x
What is the answer to 2x-3y equals 4 y equals 8?
Since 2x-3y=4y=8 we can say that 4y=8 therefor y=2 We can also say that 2x-3y=4y and as y=2 2x-6=8 so 2x=14 and x =7 so y=2 and x=7
What is 3y plus 4y plus 6 equals 20?
y=2
What is the answer to 2x plus 4y equals -6 and x-3y equals 7 using substitution?
1) 2x + 4y = -62) x -3y = 7We can add 3y to both sides of equation 2) to getx = 3y + 7Now we can substitute 3y + 7 for x in equation 1).In other words, we replace any 'x'es in equation 1) with 3y + 7.2x is two times x, so this becomes 2(3y + 7) which is two times 3y_and_sevenEquation 1) becomes2(3y + 7) + 4y = -6or6y + 14 + 4y = -6or10y + 14 = -6Subtracting 14 from both sides,10y = -20Dividing both sides by 10,y = -2.Substituting -2 for y in equation 1),2x - 8 = -6Add 8 to both sides2x = 2x = 1Check our results with equation 2x - 3y = 71 + 6 = 7
2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
Simlify 10x-3y plus 2x-4y?
10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y
What is 2x plus 4y-5x plus 3y?
2x + 4y - 5x + 3y = 7y - 3x
Simplify 4x plus 7y plus 2x-3y equals?
6x plus 4y
10x - 3y plus 2x - 4y?
10x+2x-3y-4y=12x-7y
What is the x value 2x-3y equals -15 x equals 4y?
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
What is the order pair for 2x - 3y equals 4 and x plus 4y equals -9?
The ordered pair is (-1, -2).
How much is (2x plus 3y) plus (4x plus y)?
It is the same as: 6x+4y
Simplify the algebraic expression 4x plus 3y - 2x - 7y?
4x + 3y - 2x - 7y2x - 4y
What is the answer to 2x-3y equals 4 y equals 8?
Since 2x-3y=4y=8 we can say that 4y=8 therefor y=2 We can also say that 2x-3y=4y and as y=2 2x-6=8 so 2x=14 and x =7 so y=2 and x=7
How simplify 5x plus 3y-2x plus 4y?
3x + 7y
4y plus 4 equals 3y-5?
4y + 4 = 3y - 5 y = -9
