Answer:
-1/9(-27)=3
Step-by-step explanation:
that's my answer
Multiply the first equation by 2:-
2y + 4.6 = 0.90x
2y - 0.90x = -4.6
second equation is
-2y - 4.2x = -7.8
Adding:-
-5.1x = -12.4
x = 2.4
-2y = -7.8 + 4.2(2.4) = 2.3
x = -1.2
Answer x = 2.4 and y = -1.2
Its choice A
Product of two and a number x can be written as 2*x or simply 2x.
Now the sum of eight and the product of two and a number x can be represent as an algebraic expression 8+2x.
