Solve y equals -2 4x-3y equals 18?
y = -24x - 3y = 18 (use the substitution method)4x - 3y = 18 (substitute -2 for y, and solve for x))4x - 3(-2) = 184x + 6 = 18 (subtract 6 to both sides)4x = 12 (divide by 2 to both sides)x = 3Thus, (3, -2) is the solution of the given system of equations.
What should be added to both sides of this equation to solve for the variable 18 plus y equals 32?
You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
How do you solve the equation 3 parentheses x plus 2 parentheses equals x minus 18?
3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
What are the solutions to the simultaneous equations of 2x -3y equals 4 and 5x plus 2y equals 1?
Equations: 2x-3y = 4 and 5x+2y = 1 Multiply all terms in 1st equation by 5 and all terms in 2nd equation by 2:- So: 10x-15y = 20 and 10x+4y = 2 Subtract the 2nd equation from the 1st equation: -19y = 18 => y = -18/19 By substitution the solutions are: x = 11/19 and y = -18/19

What is the answer to this simultaneous equations 5x plus 2y equals 11 4x - 3y equals 18?
To solve the simultaneous equations (5x + 2y = 11) and (4x - 3y = 18), we can use the substitution or elimination method. By manipulating the equations, we find that (x = 4) and (y = -3). Thus, the solution to the simultaneous equations is (x = 4) and (y = -3).

Solve this system of equations 5x plus 3y plus z equals -29 x-3y plus 2z equals 23 14x-2y plus 3z equals -18?
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
How do you solve basic linear equation?
y=2x+12 7x+y=24 (as there is y in both equations you can assume that the equations are equal to each other, so substitute) 7x+2x+12=30 (solve) 9x=18 x=2 (substitute into the first equation to solve for y) y=(2x2)+12 y=16
How do you solve 2y18 to equations and equalities?
Without an equality sign the expression given can't be considered to be an equation. But if you meant: 2y = 18 then y = 9
What is the sum of two numbers is 18 their difference is 2 what are the two numbers?
Let's call the two numbers x and y. We know that x + y = 18 and x - y = 2. We can solve this system of equations by adding the two equations together to eliminate y, which gives us 2x = 20. Dividing both sides by 2, we find that x = 10. Substituting this value back into one of the equations, we can solve for y and find that y = 8. Therefore, the two numbers are 10 and 8.
What two numbers whose sum is 21 and whose difference is 15?
Let the two numbers be x and y. We have the following equations: x + y = 21 and x - y = 15. Solving these equations simultaneously, we can add the two equations to get 2x = 36, which gives us x = 18. Substituting x = 18 back into the first equation, we find y = 3. Therefore, the two numbers are 18 and 3.
What is 3x 9y -18 and -3x 10y 18 by elimination?
To solve the system of equations (3x + 9y = -18) and (-3x + 10y = 18) by elimination, we can add the two equations together to eliminate (x). This results in ( (3x - 3x) + (9y + 10y) = -18 + 18), simplifying to (19y = 0), which gives (y = 0). Substituting (y = 0) back into either equation, such as (3x + 9(0) = -18), results in (3x = -18), leading to (x = -6). Thus, the solution is (x = -6) and (y = 0).
Solve the system 6x-7y-6 18-3y-6 using the addition method by what constant should one of the equations be multiplied if the x terms are to drop outthe correct answer-3 613?
