Step-by-step explanation:
2x(3x+5)
Distribute 2x to the terms in the bracket.
2x(3x) + 2x(5)
2x × 3x + 2x × 5

6x²+10x
The answer is 6x²+10x.
Siince 2nd equation is already equal a, subsitute b-2 for a in the other equation
b-2-3b=28
-2-2b=28
add 2 to both sides
-2b=30
divide both sides by -2
b=-15
sub back
a=b-2
a=-15-2
a=-17
(a,b)
(-17,-15)
