25 + 78 = 103
4+78=82-7=75

546 + 432 - 78 + 345 = 555
36 + 78 + 198 + 475 + 620 = 1,407
That equals 199
No.567 + 78 - 56 = 589

-10 + 7x + 4x = 78 Collect like terms -10 + 11x = 78 Add '10' to both sides 11x = 88 Divide both sides by '11' 11x/11 = 88/11 x = 8 The answer!!!!!
What is 'what'???? You write it as 'unknown' or 'x' . Hence 50 + x = 128 Subtract '50' from both sides x = 78 The Answer!!!!!! (The 'What???').
