x = 4 and y = 11
You set this up like a matrix or a system of equations. This one is easy to set up as matrix
2 -3 |-25
3 4 |34
triangluate by making the bottom left number (3), 0. ie, multiply the top row by -3, and the bottom row by 2. that will let you add the results from both products to be added together isolating y. you will get y=11, so plug in y=11 into either of the other two original equations to solve for x.

What is -3x plus -18 equals 2x plus 7?
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
4x plus 35-2x plus 25 equals 6?
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
What is 7x-2x equals 7 plus -2x?
It is an equation and the value of x is 1
9x2 - 2x plus 25 equals 8x2 plus 8x?
x=5
What is 2x plus 25 equals 7x?
2X + 25 = 7X subtract 2X from each side 25 = 5X divide both sides by 5 5 = X
Equation 2x plus 5 equals 25 for x?
2x + 5 = 25 2x = 20x = 10
What is -3x plus -18 equals 2x plus 7?
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
5x plus 3y equals 31 2x plus 3y equals 25?
(2,7)
4x plus 35-2x plus 25 equals 6?
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
What is 7x-2x equals 7 plus -2x?
It is an equation and the value of x is 1
What value of x satisfies the equation 2 times x plus 5 plus 3 times x equals 25?
If you mean: 2x+5+3x = 25 then the value of x works out as 4
What value of x satisfies the equation 2x plus 5 plus 3x equals 25?
2x + 5 + 3x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
9x2 - 2x plus 25 equals 8x2 plus 8x?
x=5
How do you solve 9 plus 6x equals 25-2x?
9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
2x plus y equals 25 x plus y equals 14?
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
What is 2x plus 25 equals 7x?
2X + 25 = 7X subtract 2X from each side 25 = 5X divide both sides by 5 5 = X
What is the answer for 7x equals 2x plus 5?
The value of x is 1
