Question

quiero saber cuanto es esta ecuación 2x + 10-10= x+ 20

Answer 1

 
Simplifying -10 = x + (-20) -10 = x + -20 Reorder the terms: -10 = -20 + x Solving -10 = -20 + x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x' to each side of the equation. -10 + -1x = -20 + x + -1x Combine like terms: x + -1x = 0 -10 + -1x = -20 + 0 -10 + -1x = -20 Add '10' to each side of the equation. -10 + 10 + -1x = -20 + 10 Combine like terms: -10 + 10 = 0 0 + -1x = -20 + 10 -1x = -20 + 10 Combine like terms: -20 + 10 = -10 -1x = -10 Divide each side by '-1'. x = 10 Simplifying x = 10
