Well just substitute y (the first equation) into the second equation.
So
5x-4(5-3x)=-3
Then just solve the equation from there.
5x-20+12x=-3
17x=17
x=1
and if you need y, y=2
Answer:
5 3/5
Step-by-step explanation:
Convert 1/8 to 10/80 and 7/10 to 56/80 56/10= 5 3/5
All real numbers greater than or equal to -3
Answer:
The smallest number is 88
Step-by-step explanation:
Let
x ----> the first consecutive even number
x+2 --->the second consecutive even number
we know that
The linear equation that represent this problem is given by

solve for x

so

therefore
The smallest number is 88
