Answer:A
Step-by-step explanation:
Just took the ed test
Simplifying
9x = 12y
Solving
9x = 12y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '9'.
x = 1.333333333y
Simplifying
x = 1.333333333y
Answer:
Answer is x = 10
Step-by-step explanation:
We have given
2(x+3) - 4x = 3(2 -x) +10
We need to solve above equation for x.
2(x+3) - 4x = 3(2 - x) + 10
2x + 6 -4x = 6 - 3x + 10
Bring all x terms to the left and other terms to the right
We get,
2x - 4x + 3x = 6 + 10 - 6
5x - 4x = 10
x = 10
Hence we get x =10
The standard form of a quadratic equation is :
ax² + bx + c = 0
And the quadratic formula is:
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} .
So, first step is to compare the given equation with the above equation to get the value of a, b and c.
So, a = -1, b = 2 and c = 1.
Next step is to plug in these values in the above formula. Therefore,
So, x =
