Answer:
1
Step-by-step explanation:
18x12 = 216
so now lets multiply the area of the door 7x3 21 216-21=195
7(x4) = 8-x
x= -2
your first step would be to move your 3x to the other side of the equation by adding 3x to both sides after this your equation should look as follows: 7(4+x)+3x=8 2nd: you should distribute your 7 to the numbers inside of the parentheses and combine like terms to get 10x+28=8 then you move your 28 to the other side by subtracting 28 and you will get 10x=-20 divide by ten to get the answer which is x=-2
Edit: Sorry for the answer before. I realised my mistake.
