x - y = 6
3y = x + 22
you need to solve these equations simultaneously.
first get all your x's and y's on the same side.
x - y = 6
3y - x = 22
if you add these two equations together, the x's will cancel as one is positive and the other negative.
x - y + 3y - x = 22 + 6
2y = 28
y = 14
then substitute y is 14 into one of the original equations to find x
x - 14 = 6
x = 20

Use the substitution method to solve the following system of linear equations -3x-y equals 3 -3x-5y equals -21?
From first equation, -y = 3x + 3. Substitute in second equation: -3x + 5(3x + 3) = -21 ie 12x = -36 so x = -3 and y = -(-9 + 3) = 6. Easier method: subtract first equation from second giving -4y = -24 so y = 6, this in first equation gives -6 = 3x + 3, ie 3x = -9 so x = -3
What number subtracted from 8 gives you 2 09?
8.00 − 5.91 = 2.09 (Method is to first subtract 2.09 from 8.00, which equals 5.91 If you then subtract 5.91 from 8.00 the answer will be 2.09)

What is the answer to x-y equals 2 2x plus 3y equals 4 using multipication and addition method?
x - y = 2 : Equation 1 2x + 3y = 4 : Equation 2 Multiplying Equation 1 by 3 gives 3x - 3y = 6 : Equation 3 Adding Equation 2 to Equation 3 gives 5x = 10 Dividing both sides by 5 gives x = 5 Substituting x=5 into Equation 1 gives 5 - y = 2 Therefore y = 3. Our final answer is therefore x=5 and y=3
