Solve for x2:<br><br> y2 − y1 = m(x2 − x1)<br><br><br> this is literal equations btw
blondinia [14]

Answer:

x2 = y2/m - y1/m + x1

Step-by-step explanation:

Expand

y2 - y1 = mx2 - mx1

Rearrange

y2 - y1 + mx1 = mx2

Divide both sides by m to make x2 on its own

y2/m - y1/m + x1 (m's cancel out) = x2

Hence:

x2 = y2/m - y1/m + x1

If 2x + 5y = 10 and x = 3y + 1, what is 11x + 11y?
saul85 [17]
You have to solve the two equations by eliminating x or y 
<span>2x+5y=10 </span>
<span>x-3y=1 </span>
<span>Multiply all terms of second equation by two and subtract from first equation, thus eliminating x </span>

<span>2x+5y-2x+6y=10-2 </span>
<span>11y=8 </span>
<span>y=8/11 </span>
<span>x=3y+1=3* 8/11+1=25/11 </span>
<span>11x+11y= 11*25/11+ 11*8/11 </span>
<span>= 25+8=33</span>
