Since x= y+7

So you just blog in x in the second equation

Y+7= 9-y

By adding y to each side

2y+7=9

Then subtract 7 from each side

2y=2

Divide each side by 2

Y=1

Then blog in Y in the first equation

X=y+7

X= 1+7=8

andreev551 [17]

Answer:

resistance: (2r +5)
current: (3i +4)

Step-by-step explanation:

The factors of the given expression are ...

6ir +15i +8r +20 = (3i +4)(2r +5)

Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...

resistance: (2r +5)

current: (3i +4)
