Question 112964
Let the numbers be x and y
A) 3(x+y)=2(x-y)+5
B) (x+y)/2=x-y+2
.
A) 3x+3y=2x-2y+5
x+5y=5
B)x+y=2x-2y+4 multiply both sides by 2.
-x+3y=4
*[invoke linear_substitution "x", "y", 1, 5, 5, -1, 3, 4]
Check:
A)
3(-.625+1.125)=1.5
2(-6.25+1.125)=-3.5 difference of 5
.
B)
(-.625+1.125)/2=.25
