What else can I help you with?
4x2 - 12x plus 9 equals 5?
4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
4x-2 plus 5 equals 2x plus 8?
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
What is the factor of equals X2-2x-15?
x2-2x-15 = (x+3)(x-5) when factored
What is the Value of 3x - 4 if 2x plus 1 equals -5?
2x + 1 = -5 so 2x = -6 so that x = -3 Then 3x - 4 = 3*(-3) -4 = -9 - 4 = -13
What is three equals two times x plus five?
3 = 2x + 5 -5 -5 -2 = 2x ---------- 2 x = -1
2x-3 equals x plus 5?
2x-3 = x+5 2x-x = 8 x = 8
What is the solution of 2x plus 3 equals 3x plus 5?
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
Why does 2x-3 equals 2x-5 have no solution?
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
The line with equation 2x-3y equals 5 has slope?
Solve for y.2x - 3y = 52x - 2x - 3y = -2x + 5-3y = -2x + 5-3y/-3 = -2x/-3 + 5/-3y = (2/3)x - 3/5Clearly you see that the slope is 2/3.
-2x divided by 3 -5 equals 5?
-2x/3 - 5 = 5 Add 5 to both sides: -2x/3 = 10 Multiply both sides by 3: -2x = 30 Divide both sides by -2: x = -15
How do you solve for x 2x plus 5 equals 11?
If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
4x-3 equals 2x plus 5?
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
What is 5 plus x equals 2x - 3?
comooon it's very easy !!x - 3 = 2x + 5x - 2x = 5 + 3-x = 8X = -8
What is the answer for this equation 2x-3 equals x plus 2?
2x-3=x+2 2x-x=2+3 x=5
What is the answer for 2x-5 equals 3?
Adding 5 on both sides, we get2x-5+5 = 3+52x = 8Dividing both sides by 2x = 4
2X plus 2 equals X plus 5?
2x+2=x+5 x=3
