Solve this equation using addition method -8x plus 3y equals -5 and 8x subtract 2y equals 6?
x=1, y=1
What is 6a - 5b equals 9 using addition method?
You need two equations to use the addition method.
Solving systems by elimination method X plus y equals 2 and 2x plus 7y equals 9?
Double first equation: 2x + 2y = 4 Subtract this from second equation giving 5y = 5 so y = 1 and x = 1
How do you solve each system by the addition method?
solve system equation using addition method 3x-y=9 2x+y=6
Solve the equation by substitution method x-y equals 5?
x+y=5
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)
How do you Solve this system of equations using the addition method 6a - 5b equals 9 2a plus 5b equals 23?
the answer
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
How do I solve whole number equations that contain addition or subtraction?
The answer depends on the equation: there is no single method which can be used for all equations.
Solve py plus qz equals pq by charpit method in partial differential equation?
z=pq
Completing the square method?
Completing the square is a method to solve quadratic equations. To use this method you take the number without a variable and subtract it from both sides, so that it is on the opposite side of the equation. Then add the square of half the coefficient of the x-term to both sides. This will give you a perfect square equation to solve for.
2x-3y equals -2 4x plus y equals 24 use substitution method and work the system of equation?
