Question

4(5 + 2x) -5 = 3(3x + 7)

Answer 1

Answer:

x =  -1

Step-by-step explanation:

The first step is get rid of the numbers outside this (). So we will get

20+8x=9x+21 (multiplication) And we can get rid of one side of x by subtract 8x on both sides, an then we will get 20= x+21

And we can move the numbers to one side by subtract 21 on each side, and we will get -1=x

And rewrite it:

x = -1

That's the answer.
