Question 302675
Set-Up:
-----------
Equation 1: {{{A = B + 1}}}
Equation 2: {{{A = 2B - 11}}}
-----------
Solution:
-----------
Since both equations are equal to A, you can set them equal to each other
{{{B + 1 = 2B - 11}}}
Subtract B form both sides
{{{1 = B - 11}}} Add 12 to both sides
{{{highlight(12 = B)}}}
Now plug 12 back into one of the eqautions to solve for A
Equation 1: {{{A = B + 1}}}
{{{A = (12) + 1}}}
{{{highlight_green(A = 13)}}}
