(3, 2)
Simplify 5m plus 7-2m-1?
5m + 7 - 2m - 1 = 3m + 6
Did you hear about math worksheet page 167?
3x-5y=7 5x-2y=-1
What is the solution to 2y equals 5x - 1 x equals y plus 2?
If those are two different equations, such that 2y=5x-1 and x=y+2, then you subsitute y+2 in for x in the first equation, and when you solve the whole thing, you get that x=-1 and y=-3, or the point (-1,-3)
What is the ordered pair for 2x plus 5y equals 16 plus -5x minus 2y equals 2?
2x + 5y = 16 + (-5x) - 2y = 2 That gives 2x + 5y = 2 . . . . . . . . . . (I) and -5x - 2y = - 14 or 5x + 2y = 14 . . . . (II) (I)*5: 10x + 25y = 10 (II)*2: 10x + 4y = 28 Subtracting the second from the first, 21y = -18 so y = -18/21 = -6/7 and then by (I) x = 1 - 5y/2 = 1 - 5/2*(-6/7) = 1 + 15/7 = 22/7 So the ordered pair is (22/7, -6/7)
5x plus 2y equals 19 x - 2y equals -1?

What is the answer to this problem 5x plus 2y equals 19 and x-2y equals -1?
x = 3 and y = 2
3x plus 2y equals 20 and 5x-2y equals 1?
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
2y plus 5x 13 2y and ndash 3x 5?
If you mean: 2y+5x = 13 and 2y-3x = 5 then x = 1 and y = 4
What is the ordered pair of 2y 5x 13 2y - 3x 5?
If you mean: 2y+5x = 13 and 2y-3x = 5 then it works out that x = 1 and y = 4
What is the answer to 5x plus y21 x6-2y?
If you mean 5x+y = 21 and x = 6-2y then x = 4 and y = 1
How do you solve for 5x plus y equals 1 and 3x plus 2y equals 2?
For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x
How do you solve 5x plus 1 equals 20?
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
X plus 2y equals -1 5x - 4y equals 16?
x+2y = -1 and 5x-4y = 16 Solving the simultaneous equations gives: x = 2 and y = -1.5
Solve 5x plus 2y equals 19?
There are two answers to this, because you did not give two equations. x = 1 and y = 7 x = 3 and y =1
5x plus 3y equals 17 5x - 2y equals -3?
Multiply the bottom equation by -1
5x plus 2y equals 1 -x - y equals -2?
