Answer:
here's what we know:
a + b = 72
a - b = 26
 
We can use the elimination method to solve this problem:
a + b = 72
a - b = 26
---------------
2a = 98
Divide both sides by 2:
a = 49
 
So we now have:
49 + b = 72
and:
49 - b = 26
 
Subtract 49 from both sides:
b = 23
and
-b = -23 (multiply both sides by -1) → b = 23

2(7-7x) = 2x + 4
14 - 14x = 2x +4
16x = 10
x = 10/16
x = 0.625
2[-(7-7x)] = 2x + 4
-14 +14x = 2x + 4 
12x = 18
x = 18/12
x = 1.5
answer:
solutions x = 0.625 and x = 1.5
