x would be 9.
10x+3=93
10x=90 (after you subtract 3)
x=9 (after you divide both sides by 10)
It is: x2-10x+21 = 0 and the value of x is 3 or 7 when solved
y=-10x-4
10x - 78 = 1, 10x = 79, x = 7.9
x=-8
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
It is a linear equation in x. 10x = 7x + 15 3x = 15 x = 5
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
We want to answer the equation 10x = 350 This can be done by dividing both sides by 10. That makes the equation x = 35. Thus the value of x that makes 10x=350 is 35.
When x = -5
If 10x + 6y = 24, y = (24 - 10x)/6 = 4 - (5/3)x. The slope of a line with an equation written in this format is the coefficient of x, therefore -(5/3).
The roots of the equation are [5 +/- sqrt(11)]/2 = 4.158 and 0.842
10x + 6 is an expression, not an equation nor an inequality. An expression doesn't have an answer! ================================ 10x + 6 is not an equation, and it doesn't ask a question. It has a numerical value, but we can't know what that is until we know the value of 'x'. Even then, if 'x' changes, then the value of (10x + 6) immediately changes too.
