That's not an equation. It need a = sign before you can solve it. However you can simplify it by combining like factors
it is not an equation (there no equality in it!)
Solve the equation for x, and enter your answer in the box below.
variable equation solve it test it
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
There is no equation to solve, only an expression.
You can't solve it - you only have one equation and two unknowns. You need 2 equations to solve this.
Try like this:4 = 3w - 5Add 5 to each side of the equation:9 = 3wDivide each side by 3:3 = w
Without an equality sign the given expression can't be considered to be an equation
7w + 2 = 3w + 94 Subtract 3w from both sides: 4w + 2 = 94 Subtract 2 from both sides: 4w = 92 Divide both sides by 4: w = 23
Expressed as an algebraic equation, this would equal 3w.
3w + 4 = 24 .......- 4... - 4 .......3w = 20 .......÷3 ...÷3 .........w = 20/3 or 6.6667
3w^2 - 8w + 4 = (3w -2) (w-2) So 3w-2=0, then 3w=2, so w=2/3, w-2=0, so w=2. Your solutions are w=2/3 and w=2.
5w - 5 = 8w - 25 -5 + 25 = 8w - 5w 20 = 3w 6 2/3 = w
The roots (or solutions) are the numbers that 'w' must be in order to make the equation true.Since the highest power of 'w' in the equation is the first power, there's only one solution.3w - 14 - 6 = 21Combine the -14 and the -6 on the left side:3w - 20 = 21Add 20 to each side:3w = 41Divide each side by 3 :w = 41/3 = 132/3
The perimeter is the total of all the sides added up, which is two lengths and two widths. We can write the equation 66 = 2w + 2ℓ where 66 is perimeter, w is width, and ℓ is length. We can also write equation ℓ = 3w because the length is three times greater than the width. We can replace ℓ with 3w in the first equation because the second equation tells us they are the same thing: 66 = 2w + 2*(3w) Now we have an equation with one variable, so we can solve for that variable (w): 66 = 2w + 2*(3w) 66 = 2w + 6w 66 = 8w Divide both sides by 8: 8.25 = w The width is 6.6. We can plug that 6.6 into the equation ℓ = 3w to find the length: ℓ = 3*8.25 ℓ = 24.75 The length is 24.75. So the width is 8.25 and the length is 24.75.
That depends entirely on what the width is. If you call the width (in feet) w, then the length in feet would be 3w+2 With more information either the perimeter or the area of the rectangle you could solve the problem A = lw A = (3w+2)w replace A with area and solve or P = 2(l+w) P = 2((3w+2)+w) replace P with the perimeter and solve
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
