Question

Solve for x. 5x - 4 = -3x + 12

Answer 1

Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{x = 2}}}}}$

Step-by-step explanation:

$\sf{5x - 4 = - 3x + 12}$

Move 3x to left hand side and change it's sign

⇒$\sf{5x + 3x - 4 = 12}$

Move 4 to right hand side and change it's sign

⇒$\sf{5x + 3x = 12 + 4}$

Collect like terms

⇒$\sf{8x = 12 + 4}$

Add the numbers

⇒$\sf{8x = 16}$

Divide both sides of the equation by 8

⇒$\sf{ \frac{8x}{8} = \frac{16}{8} }$

Calculate

⇒$\sf{x = 2}$
