Question 177520
the answer to the substition method of 2x+3y=5
x=4=2y
-----------------
The substitution method is neither a question nor a problem, so it doesn't have an answer.
You can use the substitution method so solve for x and y in the pair of equations, tho.
2x+3y=5
x=4=2y
The substitution could be used, but the 2nd equation has 2 equal signs.
x=4=2y --> x = 4
y = 2
That doesn't fit in the 1st equation.  There's something wrong, and I think it's your presentation of the problem.
