Let's use the "elimination by addition/subtraction" method to solve this system for x and y.
<span> -8x=72-16y
4x=-92+16y <= Mult. all 3 terms by 2: 8x = - 184 + 32y
Now combine the following, column by column:
</span><span> -8x= 72-16y
</span>8x = - 184 + 32y
-----------------------
0 = -112 + 16y. Solving for y, 16y = 112, and y = 7.
Now subst. 7 for y in either of the original equations and calculate x:
<span>4x=-92+16(7) => 4x = -92 + 112 = 20. Then x = 5.
Solution is 5, -7 (or, better written) (5, - 7).</span>
Answer:
The correct answer is b=9
G (z)= 3z - 6
3(-3) - 6 = -15 = (-3,15)
3(-2) - 6 = -12 = (-2,-12)
3(-1) - 6 = -9 = (-1,-9)
3(0) - 6 = -6 = (0,-6)
3(1) - 6 = -3 = (1,-3)
3(2) - 6 = 0 = (2,0)
3(3) - 6 = 3 = (3,3)
For the table separate the equations in a column by each equal sign. For each row separate with every line.
Hope this helps
