Y equals -x plus 12x-y equals 5 solve by substitution?
17
y - (x - 4) + x use x = 13, and y = 1?
The answer is 5
What is the sum of 2 numbers that equals 13 and their difference is 5?
x + y = 13 x - y = 5 ------------ 2x = 18 x = 9 y = 4 Verification: 9 + 4 = 13 and 9 -4 = 5
Solution for 2x plus y equals 5 and x-3y equals 13 by substitution?
2x + y = 5 so y = 5 - 2x; This gives x - 3(5 - 2x) = 13 ie x + 6x = 13 + 15 so x = 4 and y must be -3
What is 2 sets of ordered pairs for y equals 6x-13?
#1). x = 0, y = -13 #2). x = 1, y = -7 #3). x = 2, y = -1 #4). x = 3, y = 5 #5). x = 4, y = 11
What two numbers equal 13 but when multiplied equal -90?
103
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.
What is the ordered pair for y4x-2 yx plus 13?
If you mean: y = 4x-2 and y = x+13 then x = 5 and y = 18
How do you solve x plus y equals 8 and 2x minus y equals 5 using the addition method?
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
Which pairs of points both lie on lines of equation 3x - y equals 2?
1
How do you Solve the equation for 3x-5y equals 13?
Solved for y: y=(3x-13)/5 Solved for x: x=(5y+13)/3
What is the answer to x plus y equals 8 and 2x-y equals 5?
x + y = 82x - y = 5-------------------- add together to eliminate y3x = 13x = 13/3Substitute for x in one of the original equations:(13/3) + y = 8y = 24/3 - 13/3y = 11/3x=13/3 & y=11/3
