Oh, dude, we've got some math up in here! So, to solve this thrilling equation, you just need to get all the y's on one side. Subtract 5y from both sides, and you get 3y on the left. Then, subtract 7 from both sides, and you find out y equals -2. Boom, math wizardry at its finest!
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
f(x)= (4 - 5y)/8 f(y)= (4 - 8x)/5
1. 6x - 5y = 22 2. 5x - 9y = -1 1 times 5: 30x - 25y = 110 2 times 6: 30x - 54y = -6 Subtract : 29y = 116, so y = 4 and x therefore = 7
4x + 5y = -8 is an equation with two variables. While you can solve for y = something, you won't come up with a single number. For example, 4x + 5y = -8 5y = -4x - 8 y = -4x/5 - 8/5. And you can do the same for x = something in terms of y.
2y = 4x - 16 5y = 4x + 8 Subtract the first equation from the second: 3y = 24 so that y = 8 Substitute this into the first equation: 16 = 4x - 16 ie 32 = 4x so that x = 8 So the solution is (8, 8)
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
If y equals 3, 7 - 5y would be:7 - 5(3)Simplify.7 - 15 = -8.In conclusion, 7 - 5y = -8.
8 + y = 7 + 5y <----they are equal to the same number so are equal to each other 4y = 1 y = 0.25
5y+8=7y 2y=8 y=4
8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
y=8
Y=30
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
13y+3z+8
If: 3y+8 = 5y-20 Then: 3y-5y = -20-8 So: -2y = -28 And: y = -28/-2 => y = 14
It is a linear equation with a single variable, y.
