Answer:
First solve for x
then substitute
Step-by-step explanation:
2x + 6 = 3y + 6
2x = 3y
If then =
Subtract 10x
10x + y = -19
10x + 3y = -17
You would get:
-2y = -2
Two negatives make a positive number! Divide
y = 1
Plug in
10x + (1) = -19
10x = -20
Divide
x = -2
Your solutions are
x = -2
y = 1
2.3+3.1+1= 6.4
25÷6.4= 3.90625
