I think you have to add the weights of the cargo ship
#3 3.4w-0.4w+4.6w+5=-7.6
8.2w+5=-7.6
8.2w=-7.6-5
8.2w=-12.6
W=-12.6÷8.2
W=-1.53658 I'm working on otherc2
Answer:
<h2>x = 4</h2><h2>y = 3</h2>
Step-by-step explanation:
2x - 3y = - 1 ………… Equation 1
y = x - 1 ….……….… Equation 2
To solve using substitution , substitute equation 2 into equation 1
That's
2x - 3( x - 1) = - 1
2x - 3x + 3 = - 1
- x = - 1 - 3
- x = - 4
Multiply through by - 1
We have
<h3>x = 4</h3>
Substitute x = 4 , into y = x - 1
We have
y = 4 - 1
y = 3
We have the answers as
x = 4
y = 3
