If x=2 what's 3x+5-4x

You need to substitute all "x"s for "2" in the equation:



and now we count:



so the solution is 3.

(3*2+5-4*2= (here i multiplied 3*2, which is six)

6+5-4*2=(here i added 6 and 5 which is 11)

11-4*2= (here i multiplied 4 and 2 which is 8

11-8=3

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
