Answer:
x=11
Step-by-step explanation:
(x-3)/2=(x+1)/3
multiply (x-3)(3) and 2(x+1)
3(x-3)=2(x+1)
3x-9=2x+2
Get the variables on one side and numbers on another
3x-2x=3+9
x=11
x=23
a²+b²=c²
25+144=169
the square root of 169 is 13
add 10 to get x
23

sory
3(2d - 7) = (2 + 4d)2
distribute
3*2d -3*7 = 2*2 +2*4d
multiply
6d -21 = 4 +8d
subtract 6d from each side
6d-6d-21 = 4 +8d-6d
-21 = 4+2d
subtract 4 from each side
-21 -4 =4+2d-4
-25 =2d
divide by 2
-25/2 =d
It is b 4.2 al you have to do is subtract 12.2 from 8 so like if you have g-86=43 all you have to do is the opposite. G =129
