13 + 15 = 28
The sum is 93.
13 + 16 + 18 + 20 + 21 + 26 + 27 + 27 + 28 + 36 + 39 + 42 + 43 = 356
w = 13 add 28 to 180, then subtract 13 from 180 to balance equation. Then 4w + 11 w = 195. Add 4w + 11w =15w, so 15w=180, divide 180 by 15, w = 13 4(13) -28 + 11(13) + 13 = 180
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
-28
13 + 15 = 28
Yes that is correct
basically you asked what -28+21 which equals -7
The sum is 93.
x = 13
120 + 13 + 3 + 8 + 2 + 2 + 353 + 42 + 20 + 28 + 87 + 8 + 10 = 696
13 + 16 + 18 + 20 + 21 + 26 + 27 + 27 + 28 + 36 + 39 + 42 + 43 = 356
-15 + 6y = 13 6y = 13+15=28 y=28/6=4.66 or 4 and 2/3
w = 13 add 28 to 180, then subtract 13 from 180 to balance equation. Then 4w + 11 w = 195. Add 4w + 11w =15w, so 15w=180, divide 180 by 15, w = 13 4(13) -28 + 11(13) + 13 = 180
13
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
