5(–9a–1)+7=0

-9a-1=-7/5

9a+1=7/5

9a=7/5 +1

a=(7+5)/(5×9)=35/45=7/9

4x -5 = 2(2x +1)<br> I need help

Nostrana [21]

Answer:

No Solution

Step-by-step explanation:

$4x-5=2\left(2x+1\right)$

Expand:

$4x-5=2* \:2x+2* \:1$

$4x-5=4x+2$

Add 5 to both sides:

$4x-5+5=4x+2+5$

$4x=4x+7$

Subtract 4x from both sides:

$4x-4x=4x+7-4x$

$0=7$

No solution as this is false.
