Answer:

Solve for x:
x = (3y+1)/(4y-2)

Evaluate x for y = 1:
x = 2

Explanation:


Original:y=(2x+1)/(4x-3)\\Multiply\ out\ the\ denominator:(4x-3)*y = 2x+1\\Distribute: 4xy - 3y = 2x+1\\Group\ Like\ Terms:4xy-2x = 3y+1\\Factor\ Out\ x: x(4y-2) = 3y+1\\Divide\ to\ get\ x\ alone:x = (3y+1)/(4y-2)\\\\Plug\ in\ the\ value\ for\ y:x = (3(1)+1)/(4(1)-2)\\Multiply:x = (3+1)/(4-2)\\Add:x = (4)/(2)\\Simplify/Divide:x=2
