Answer:
=2
Step-by-step explanation:
w= 2
3-2w+4w=7. We move all terms to the left: 3-2w+4w-(7)=0, Then we add all the numbers together, and all the variables: 2w-4=0. After, we move all terms containing w to the left, all other terms to the right: 2w=4, w=4/2
w=2
30:1
45*12 = 540
540/18 = 30
48
y=6x
y=6(8)=48
