-2x+3y+14 and x+2y+7 1. x+2y+7=0 2. x= -2y-7 3. (substitute new equation in for x) -2(-2y-7)+3y+14=0 4. (distribute) 4y+14+3y+14=0 5. (combine like terms) 7y+28=0 6. (subtract 28) 7y= -28 7. (28 divided by 7 to solve for y) y= -4 8. (substitute -4 value for y) x+2(-4)+7 9. (solve for x value) x-8+7 x-1=0 x=1 10. (answer check) -2(1)+3(-4)+14= 0 (1)+2(-4)+7=0

What is the solution to this system of equations 6x-3y -33 2x y -1 using substituition?
If you mean: 6x-3y = -33 and 2x+y = -1 Then solving the simultaneous equations by substitution: x = -3 and y = 5
What is the substitution for 2x plus 7y -1 and 4x-3y -19?
If you mean: 2x+7y = -1 and 4x-3y = -19 then by substitution x = -4 and y = 1
What is Solve By Substitution y0.5x 2 -y-2x 4?
To solve the following equation by substitution, we need to have the equal sign. This will help us group the knowns and the unknowns.
Help me solve this equation by substitution. x-5y equals 10 2x-10y equals 20?
what is the solution of x-5y=10 and 2x-10y=20
What is the solution of the system Use substitution. y equals x plus 6 y equals 2x?
If: y = x+6 and y = 2x Then: x+6 = 2x And: 6 = 2x-x => 6 = x So: x = 6 and y = 12
