Answer:
x-1 = 0 or x-7 =0
x=1 or x=7
Step-by-step explanation:
(x-1) (x-7) =0
Using the zero product property
x-1 = 0 or x-7 =0
x-1+1 =0 +1 or x-7+7 =0+7
x=1 or x=7

Answer:
<h2>x = -4</h2><h2>y = -4</h2><h2 />
Step-by-step explanation:
-3x + 7y = -16 (-3) to eliminate x
<u>-9x + 5y = 16</u>
<u> 9x - 21y = 48</u>
-16y = 64
y = 64/-16
y = -4
substitute y= -4 into eq. 1
-3x + 7y = -16
-3x + 7(-4) = -16
-3x = -16 + 28
x = 12 / -3
x = -4
<u> check:</u>
-3(-4) + 7(-4) = -16
- 16 = -16 ok
-9x + 5y = 16
-9(-4) + 5(-4) = 16
16 = 16 ok
