taurus [48]

Answer:

See below.

Step-by-step explanation:

$3+x=ax$ (Given)

$x=ax-3$ (Subtracted 3 on both sides)

$x-ax=-3$ (Subtracted ax on both sides)

$x(1-a)=-3$ (Factor out x from x - ax)

$x=-\frac{3}{1-a}$ (Divided 1 - a on both sides)

Answer:

$10x^{2}-34$

Step-by-step explanation:

Because we are told equivalent expressions for y and z we can plug those in to 2(y+z).

$2((3x^{2}+x^{2}-5)+(x^{2}-12))$

Then simplify by combining like terms of the expressions. Values ending in x^2 can be combined with each other.

$2(5x^{2}-17)$

Now we can distribute the 2 by multiplying each value in the parentheses by 2.

$10x^{2}-34$

Can anyone solve this algebra 2 problem? <br> 15^2x-3 = 245<br> Please show work.

DochEvi [55]

15^2x is 225x. So, we have 225x-3=245. Adding three to both sides, we get 225x=248. Dividing by 225, we have x=248/225.
