X=21

5x(-3x) -2= 3x(-3x) +40

2x-2(+2)=40(+2)

2x=42

X=21

Answer:

[tex]x=21[/tex]

Step-by-step explanation:

[tex]5x-2=3x+40[/tex]

Add 2 to both sides:

[tex]\hookrightarrow 5x-2+2=3x+40+2[/tex]

[tex]\hookrightarrow 5x=3x+42[/tex]

Subtract 3x from both sides:

[tex]\hookrightarrow 5x-3x=3x+42-3x[/tex]

[tex]\hookrightarrow 2x=42[/tex]

Divide both sides by 2:

[tex]\hookrightarrow \frac{2x}{2}=\frac{42}{2}[/tex]

[tex]\hookrightarrow x=21[/tex]
