For the following system use the second equation to make a substitution for y in the first equation. 3x+y=1 y+4=5x What is the resulting equation? 3x+5x-4=1 3x+5x+4=1 3x+4-5x=1

To solve this problem, we need to use the second equation to make a substitution for y in the first equation.<br /><br />Given:<br />$3x + y = 1$<br />$y + 4 = 5x$<br /><br />Step 1: Solve the second equation for y.<br />$y + 4 = 5x$<br />$y = 5x - 4$<br /><br />Step 2: Substitute the expression for y into the first equation.<br />$3x + y = 1$<br />$3x + (5x - 4) = 1$<br />$3x + 5x - 4 = 1$<br /><br />Therefore, the resulting equation is:<br />$3x + 5x - 4 = 1$
