What is the solution for 15 equals 5x?
5x = 15 so x = 15/5 = 3
What should you do to eliminate the y-term from the top equation 15x plus 7y equals 4 5x plus 7y equals 2?
15x+7y = 4 5x+7y = 2 Subtract the bottom equation from the top equation to eliminate y which will leave you with: 10x = 2 Divide both sides by 10 to find the value of x: x = 2/10 = 1/5 in its lowest terms. Substitute the value of x into the original equations to find the value of y: Therefore: x = 1/5 and y = 1/7
What is a solution to 5x-3 equals 37?
5x-3=37 (Original Equation) 5x=40(Add 3 to the right side) x=8(Divide 40 by 5)
What is the solution to this equation x plus 12 equals -5?
7
-6y plus 3 equals -7y plus 8?
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
What is the system of equations and enter the solution as an ordered pair 4x 7y equals 47 5x-4y equals -5?
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
How do you rewrite this equation so that y is a function of x 1 plus 7y equals 5x-2?
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
What is 5x-9y equals 7 7y-3x equals -5?
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
What is the x and y intercepts of 5x-7y equals -35?
5x - 7y = -35At the x-intercept, y=0:5x = -35x = -7At the y-intercept, x=0:-7y = -35y = 5
2x plus 6 equals -6 5x plus 7y equals 1?
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
What is the ratio between x and y in 5x equals 7y?
5x = 7y , we divide both side by 'y' 5x/y = 7y/y (y will now be deducted) 5x/y = 7 x/y = 7/5 Therefore, x:y = 7:5
What are the 2 possible answers for 5x plus 7y equals 1500?
This is a linear equation. You can transform this into the form y = as follows: 5x + 7y = 1500 Subtract 5x from both sides: 5x (-5x) + 7y = 1500 (-5x) 7y = 5x - 1500 Then divide both sides by 7: 7y/7 = (5x - 1500)/7 y = (5/7)x - (1500/7) In order to find the zeros for the equation, you can simply substitute 0 for one variable at a time, and then solve the equation for the other variable. If we set y = 0, 0 = (5/7)x - (1500/7) (1500/7) * (7/5) = x x = 300 So (x = 300, y = 0) is one solution. 5x + 7y = 1500 Substituting 0 for x, we get: 7y = 1500 y = (1500/7) = approximately 214.29 The second solution is (x=0, y=214.29)
If x equals 6 and y equals 7 then 5x plus 7y equals?
The answer is 79. Since you know the values of x and y, you can simply substitute them into the equation to find the answer. x = 6 y = 7 5x + 7y = 5(6) + 7(7) = 30 +49 = 79
How do you solve 10x-7y equals -6 5x plus 7y equals 81 in an order pair?
10x-7y = -6 5x+7y = 81 Add both equations to eliminate y: 15x = 75 Divide both sides by 15 to find the value of x: x = 5 Substitute the value of x into the original equations to find the value of y: Therefore: x = 5 and y = 8
What slope o the parallel line of -5x-7y-6?
Slope is found by this form. Y = mX + c ( m = slope ) - 5X - 7Y - 6 = 0 ( I assume this is what you mean ) - 7Y - 6 = 5X - 7Y = 5X + 6 Y = - 5/7X - 6/7 The slope would be in this instance, - 5/7 ----------
What is the solution for 15 equals 5x?
5x = 15 so x = 15/5 = 3
What is the solution for 5x plus 15 equals 2x?
x = -5
