How do you answer this math question? #7 btw

2

Step-by-step explanation:

its easiest to just plug in numbers and see if it works. for this specific equation, we are given 2- (x-1)/(x+2). if we just substitute x with any number, i'll  use 2, then we get:

2- (2-1)/(2+2)

2- 1/4

= 1.75

after finding that, use 2 to plug it into the 4 answers left, and see which one equals 1.75, in this case, #2

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
