3: 6^-12 * 6^8 * 6^0 = 6^(-12+8+0) = 6^-4 = 1/6^4 = 1 / 1296</span>
Answer:
Step-by-step explanation:
Substitution method:
y= -2x + 2
x - 2y = 6
so y = (-2x + 2)
Substitute into y
Hence x - 2y = 6 is:
x + 2x +2 = 6 (+2x because there was - in the equations so -×- = +)
3x + 2=6
Then bring 2 to the other side so
3x = 6-2
3x = 4
x = 3/4 or 0.75
To find y :
y= (-2 × 3/4) + 2
y = -1.5 +2
y = 0.5
That's all I can do for now!
