MaxineWell, isn't that just a happy little math problem we have here! To find the value of Y, we simply need to multiply 5 by 3, which equals 15. So, Y equals 15. Just like painting a beautiful landscape, sometimes all it takes is a few brushstrokes to reveal the hidden beauty within.

What is the answer to y equals 3x plus 3 and y equals 4x plus 5?
y=3x+3 -- This could be the formula for a line, where the slope is 3 and the y intercept is (0,3). In the next line the slope would be 4 and the y-intercept would be 5
If an equation of variation where y varies directly as x and y equals 15 when x equals 5 find when x equals 19?
y = 3x y = 3*19 = 57
X plus y equals 2 and y equals 2x-13?
1. x + y = 22. y = 2x - 13Rewriting 2. as:3. 2x - y = 13Adding 1 & 3 gives:4. 3x = 15x = 5Substituting x = 5 into 1. gives:5 + y = 2y = 2 - 5y = -3Checking values by substituting x = 5 and y = -3 into 2 gives:-3 = (2 * 5) - 13-3 = 10 - 13-3 = -3Therefore x = 5 and y = -3.
X-y equals 5 2x plus y equals 7 answer?
x - y = 5 + 2x + y = 7 => 3x + 0 = 12 => 3x = 12 => 3x/3 = 12/3 => x=4 x-y=5 2x+y=7 =>4-y=5 =>2(4)+y=7 =>y=4-5 =>8+y=7 =>y=-1 =>y=-1 So, the answer would be x=4 and y=-1
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
