<p>The solution to 1-7x<3+x is?</p>

<p>and find the x intercept of the line whose equation is 5y-3x+4=0?</p>

<p>thanks all help is appreciated</p>

<p>subtract x from both sides, giving you</p>

<p>1-8x<3</p>

<p>subtract 1</p>

<p>-8x<2</p>

<p>then divide by (-8), noting that the "less than" sign switches when dividing by negatives</p>

<p>x>(-1/4</p>

</p>

<p>at the x-intercept, y=0. so plug that in, getting you</p>

<p>-3x=-4</p>

<p>solve for x</p>

<p>x=(4/3)</p>

<p>your coordinate would be (4/3,0)</p>
