Answer is 14x

Step by step

2x + 5 = 10 - 3x

Let’s start with 2x + 5 = 7 and you bring the x with you which is 7x

Now you do 7x = 10 - 3x , equal sign is plus am guessing and then 10 - 3x is 7x so

7x + 7x = 14x

your friend rent 10chairs and 2 tables for $300. another friend rent 8 chairs and 4 tables for $360 you want to rent 12 chairs a

$x-\ cost\ of\ renting\ chair\\
y-\ cost\ of\ renting\ table\\\\
 \left \{ {{10x+2y=300\ \ \ \ \ \ \ \ \ \ \ \ } \atop {8x+4y=360\ \ \ | divide\ by\ -2}} \right. \\\\
 \left \{ {{10x+2y=300} \atop {-4x-2y=-180}} \right. \\\\+----\\addition\\\\\
6x=120\ \ \ | divide\ by\ 6\\\\
x=20\\\\
y=\frac{300-10x}{2}=150-5x=150-5*20=150-100=50\\\\
12x+3y=12*20+3*50=240+150=390\\\\
I\ am\ expected\ to\ pay\ 390\$$
