Answer:
x = -3
Step-by-step explanation:
16x − 4 + 5x = -67
Combine like terms
21x -4 = -67
Add 4 to each side
21x-4+4 = -67+4
21x = -63
Divide each side by 21
21x/21 = -63/21
x = -3
Root of 49
Solutions are 7 and -7

A negative number multiplied by itself gives positive
So -7 is also a square root of 49
6/10 + 7/12 = 142/120 = 71/60 = 1.18 (One whole number, and 11/60)
