[tex]\large\text{-4x + 10 = 50}[/tex]
[tex]\large\text{SUBTRACT by 10 to BOTH SIDES}[/tex]
[tex]\large\text{-4x + 10 - 10 = 50 - 10}[/tex]
[tex]\large\text{Cancel out: 10 - 10 because that gives you 0}[/tex]
[tex]\large\text{Keep: 50 - 10 because it helps us solve for your x value}[/tex]
[tex]\large\text{50 - 10 = 40}[/tex]
[tex]\large\text{New equation: -4x = 40}[/tex]
[tex]\large\text{DIVIDE by -4 to BOTH SIDES}[/tex]
[tex]\mathsf{\dfrac{-4x}{4}=\dfrac{40}{-4}}[/tex]
[tex]\large\text{Cancel out: }\mathsf{\dfrac{-4}{-4}}\large\text{ because that gives you 1}[/tex]
[tex]\large\text{Keep: }\mathsf{\dfrac{-40}{4}}\large\text{ because it helps find x}[/tex]
[tex]\mathsf{\dfrac{-40}{4}= -40\div4 \rightarrow \bf -10}[/tex]
[tex]\boxed{\boxed{\large\text{Answer: \bf x = -10}}}\huge\checkmark[/tex]
