-18 < 5x - 3 Isolate/get x by itself, first add 3 to both sides of the equation
-18 + 3 < 5x - 3 + 3
-15 < 5x Divide 5 on both sides
-3 < x Your answer is A
You flip the sign [</>] if you multiply or divide a negative number to both sides of the equation.
Step-by-step explanation:
(3,2) is the solution to both equations because if you substitute the the x and y values you get a true statement for example
6(3) + 7(2) =32
18 + 14 = 32
32=32
that is a true statement
you can do the same with system B
8(3) +8(2)=40
24 + 16 = 40
40 =40
which is a true statement
Y = 5
x = 5
good luckkkkkkk
