Solution
=14
Step-by-step explanation:
<h2>
3x-12=2x+2</h2><h2>
3x-12=2x+23x-2x-12=2</h2><h2>
3x-12=2x+23x-2x-12=2x=12+2</h2><h2>
3x-12=2x+23x-2x-12=2x=12+2x=14</h2>
Solve the top equation for x and then substitute that into the bottom equation and solve for y:
Top equation: subtract 4 from both sides to get x = y - 4
Substitution and simplify:
y = 4(y - 4) - 10
y = 4y - 16 - 10
y = 4y - 26
-3y = -26
y = 26/3 or 8 1/3 or 8.333 (those are all the same but in different forms)
The length is 10
