Answer:
x = 10
Step-by-step explanation:
Assuming you mean (1/4)(4x - 24), we simplify this to obtain:
x - 6 + x = 14
Combining like terms, we get:
2x = 20. Then x = 20/2, or x = 10
Answer:
40
Step-by-step explanation:
remember PEMDAS
our equation looks like tihs: 
1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.
so now our equation looks liek this 
now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this:
6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.
