Solve 3x to the 2nd power equals 21 what are the solutions x equals and what is the x intercept?
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
What does 3x-7 equals 2?
3x - 7 = 2 3x = 9 x = 3
What is the answer to 3x plus 7 equals 3?
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
What are the exact values of x and y when 3x plus 2y equals 5x plus 2y equals 7?
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
Is 3x plus 2y equals 7 linear or nonlinear?
Linear. The only power for the variables is 1.
What number equals to the 2nd power equals 49?
The number that equals the 2nd power of 49 is the square root of 49. In this case, the square root of 49 is 7, because 7 multiplied by itself (7^2) equals 49. Therefore, the number that equals the 2nd power of 49 is 7.

3x plus 7 equals 37 x equals?
3x+7=37 -7 -7 3x=30 /3 /3 x=10
What is the answer to 3x plus 7 equals 4x?
3x+7=4x 7=4x-3x 7=x
Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
What does 3x-7 equals 2?
3x - 7 = 2 3x = 9 x = 3
What is the answer to 3x equals 7-4x and why?
3x = 7-4x 3x+4x = 7 7x = 7 x = 1
What is the answer to 3x plus 7 equals 3?
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
What are the exact values of x and y when 3x plus 2y equals 5x plus 2y equals 7?
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
Is 3x plus 2y equals 7 linear or nonlinear?
Linear. The only power for the variables is 1.
7-3x equals -4x 13?
7-3x = -4x + 13x = 6
What is 3x equals 2y plus 7 in standard form?
3x + 2y = 7
