Answer:
x =2
Step-by-step explanation:
14x - 10 = 3(4 + x)
Distribute
14x -10 = 12 +3x
Subtract 3x from each side
14x -10 -3x = 12+3x-3x
11x -10 = 12
Add 10 to each side
11x -10+10 = 12+10
11x = 22
Divide each side by 11
11x/11 =22/11
x =2
Step-by-step explanation:
at first solve first triangle with Pythagorean solving witch it c²=a²+b²
you have to change a bit so it will be c²-b²=a²
you start with 8 and 10 triangle and then you get line which is in the middle and yo udo just the same with triangle 8 and the solved side and you get x in the second triangle you have to use c²-a²=b²
When you divide by a fraction you are multiplying by the reciprocal (turn it up side down) of the fraction so...
12 times 5/6 = 72/5
