The answer is three. 6 x 3 = 18
3/9 = x/81 x = 27 So: 3/9 = 27/81
x/2 = 13 - 6 so x/2 = 7 so x = 14
5p-14 = 8p +4 take the 14 to the other side and the 8p to the other side so 5p-8p = 4 +14 -3p = 18 p = -18/3
To find the missing number in the denominator of the fraction, you can set up the equation 90/x = 18, where x is the missing number. To solve for x, you would multiply both sides by x to get rid of the denominator, giving you 90 = 18x. Then, divide both sides by 18 to solve for x, which equals 5. Therefore, the fraction is 90/5 = 18.
multiply each side by 18 so that the denominator of 18 cancels and -6X18=b therefore b=-108
Do you mean: r = (4q-5p)/9? If so then: p = (9r-4q)/-5

(4/9) x = That's not an equation. If there were a number after the 'equals' sign, then we could calculate the value of 'x'. But as it is, there's no question there, so there's nothing to solve.
7x - 18 = 66, solve for x. First step is to add 18 to both sides. So 7x = 84. Now divide by sides by 7 to get x = 12
The answer is three. 6 x 3 = 18
3/9 = x/81 x = 27 So: 3/9 = 27/81
To find out what number multiplied by 18 equals 54, you can set up an equation: 18x = 54. To solve for x, divide both sides by 18: x = 54 / 18. Simplifying the division gives x = 3. Therefore, 18 times 3 equals 54.
x/2 = 13 - 6 so x/2 = 7 so x = 14
9x+3y=-68 -2x+y=18 We are asked to solve with substitution so we first write y=18+2x. Let us substitute this into the first equation. 9x+3(18+2x)=-68 9x+54+6x=-68 15x=-68-54=-122 so x=-122/15 and y =18+2(-122/15)==18+-244/15=270/15-244/15=26/15 So the solution is (-122/15,26/15) which is an ordered pair.
Divide all terms by -1 so that:- 10b2+27b+18 = 0 (5b+6)(2b+3) = 0 So: b = -6/5 or b = -3/2
