x = 3 and y = 3 Form a simultaneous equation and solve by elimination.

-3

If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?

in order to solve this problem you have to solve for x first wich you are given the data to pre forme so x=4 and x.2=8 and 8=y and y-4=4=a=x so a+8=12 and 12=b

y/x is a constant; so first of you can solve for this constant. y/x=6/-3, or y/x=-2 y/4=-2 y=-8

y = (3 X 8) - 5 = 21.

If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3

You can't solve it. But you can simplify it to get: 4x+y=2

y=5

8

7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8

Add the two equations: 3x = 15 Divide by 3: x = 5, making y = -3. Job done.

√(2y) + 3 = 11 √(2y) = 11 - 3 = 8 √2 x √y = 8 √y = 8/√2 y = (8/√2)2 = 64/2 = 32

3y=ab. Divide by 3 to get y=ab/3

3y + 8 = 3 -8 -8 3y=-5 (3y)/3=-5/3 y=(-5/3)

Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".

x=4 y=x+3 y=4+3 y=7

If you're solving for x, then x = 3/y.

You need more information to solve for x and y. One answer is x=3 and y=1.

add 2 y to each side, divide by 3 and you get- y = x over 3

y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
