Answer : f=1
explanation : subtract 26 from both sides and then divide by -20, making f = q
16: 10(-9) +4 = -90 +4 = -86
17. 7^2 - 7 = 49-7 = 42
18. -9^2 - -9 = 81+9 = 90
19. 10(5) +4 = 54, 3*54 = 162
20. 3*5 = 15, 10(15) +4 = 154

That's cheating my guy...................
Yes, 6/8 reduces to 3/4 by dividing the numerator and denominator by 2.
Answer:
x = -1
Step-by-step explanation:
The first step is get rid of the numbers outside this (). So we will get
20+8x=9x+21 (multiplication) And we can get rid of one side of x by subtract 8x on both sides, an then we will get 20= x+21
And we can move the numbers to one side by subtract 21 on each side, and we will get -1=x
And rewrite it:
x = -1
That's the answer.
