Just put a closed circle above 5 on the # line.
Ok so right now leave the x's alone. Now add/subtract the numbers without variables which would equal to 0 since -1+4 = 3 and 3-3 =0
now 7x+x =8x so 8x is answer
The correct answer is A. 10
8 divided by 0.8 = 10
10x0.8=8
5 + 5 + 5 + 5 equals 550 lgjf8654
X + y = 8
x - y = 12
--------------add
2x = 20
x = 20/2
x = 10
x + y = 8
10 + y = 8
y = 8 - 10
y = -2
ur numbers are 10 and -2
