Answer:
That'd be
1.3b -3.2b +7.8
-1.9b + 7.8
that's the simplification
don't forget to make my answer the brainliest if it's correct
Step-by-step explanation:
3) y=4x-2
since x is already 3, simply substitute
y= 4(3)-2
y=12-2
y=10
second pair for number 3 is 10
4) y=16+7x
since y is already 37, simply substitute
37=16+7x
37-16=7x
21=7x
x=21/7
x=3
second pair for number 4 is 3
Answer:
