8(n+20) = (8*n) + (8*20)
Step-by-step explanation:
Substitute y
6x + 5(2x – 14) = -6
use distributive property
6x + 10x – 70 = -6
add terms together
16x = 64
isolate x
16x/16 = 64/16
x = 4
to find value of y, use your x value in the second equation
y = 2(4) – 14
y = -6
Verify you are correct
6(4) + 5(-6) = -6
