What is the value of the x variable in the solution to the following system of equations?

texaschic101 · Answer

substitution method will work just fine....
x - 2y = - 5 ---> x = 2y - 5
now sub 2y - 5 in for x in the 1st equation
2x + 3y = 4
2(2y - 5) + 3y = 4
now distribute the 2 through the parenthesis. Combine like terms. Get the y's on one side and everything else on the other side. Solve for y. Once you have y solved, sub that answer into either of the original equations to find x. 
Can you take it from here ?
