Answer:
g(z-1)
Step-by-step explanation:
11 × 11 = 121
1 × 121 = 121
Answer:
x = 3
Step-by-step explanation:
4(x+7)=9(x-1)+22
Begin solving for x by performing the indicated multiplication:
4x + 28 = 9x - 9 + 22
Combine the x terms:
28 = 9x - 4x - 9 + 22
28 = 5x + 13
Subtracting 13 from both sides isolates 5x:
15 = 5x. Then x = 3
Let
Eq1 : x - 2y = 12
Eq2 : 4x + 2y = 16
For substitution, we need to rearrange on of the equations so that we can substitute it in the other. Let's pick eq2 and rewrite it as 2y = 16 - 4x. We see that eq1 also has 2y in it, so we can plug this new version of eq2 in there.
3x - (16-4x) = 12
Now solve for x.
7x=28, so x=4
Plug that into either equation to solve for y. You get y=0.
So your answer is x=4, y=0
