Question 1001508
Y=1/2x -3 find the x coordinate of the point whose y
coordinate is 5 
:
y = 5. Write the equation as:
{{{1/2}}}x - 3 = 5
multiply both sides by 2, and you have
x - 6 = 10
x = 10 + 6
x - 16
:
;
Check solution in original equation, replace x with 16
y = {{{1/2}}}(16) - 3
y = 8 - 3
y = 5
