How to solve 10-3(3x-40)=-9x

Mathematics

<span>Simplifying 10 + -3(3x + -40) = -9x
 
Reorder the terms: 10 + -3(-40 + 3x) = -9x
10 + (-40 * -3 + 3x * -3) = -9x
10 + (120 + -9x) = -9x
 
Combine like terms: 10 + 120 = 130 130 + -9x = -9x
 
Add '9x' to each side of the equation. 130 + -9x + 9x = -9x + 9x
 
Combine like terms: -9x + 9x = 0 130 + 0 = -9x + 9x 130 = -9x + 9x

Combine like terms: -9x + 9x = 0 130 = 0
 
Solving 130 = 0
 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.</span>

The value of y varies jointly with the values of x and z. When x = 4 and z = 16, the value of y is 320. When x = 8 and z = 10, t
Viktor [21]

When x is doubled, y is doubled. When z is multiplied by 5/8, so is y. The result of both changes is that y is multplied by 2·(5/8) = 5/4. The new value of y is

... y = 5/4·320 = 400

_____

If you really want to, you can use the formula

... y = kxz

and compute the value of k as

... k = y/(xz) = 320/(4·16) = 5

Then use this formula with the new values of x and z:

... y = 5·8·10 = 400

Draw and label an example of two parallel lines that are perpendicular to a third line.
lara31 [8.8K]
Euclid used a somewhat different parallel postulate in trying to avoid the notion of the infinite.  He observed that when two parallel lines are intersected by a third line, called a transversal, then if you measure two angles formed by these three lines, on the same side of the transversal and between the parallels, they will add to  (that is, they will be supplementary).  Such angles are called same-side interior angles<span>:</span>
