Question 261265
The equation: {{{ X + 2*(X+1) = (X + 2) + 542}}}
Simplify the equation
{{{X + 2X + 2 = X + 544}}}
Subtract 2 from both sides
{{{X + 2X = X + 542}}}
Subtract X from both sides
{{{2X = 542}}}
Divide both sides by 2
{{{highlight(X = 271)}}}
So the numbers are; 271, 272 & 273


Check the answer
-----------------
{{{271 + 2*272 = 273 + 542}}} Simplify
{{{highlight(815 = 815)}}}
