Answer:
The sheet steel costed $22.41 per square meter
Step-by-step explanation:
About 86 because $1,100 divided by $12.75=86
Y = - 3x. Equation 1
x + y = - 4 equation 2
Putting value of y
x + (-3x) = - 4
x - 3x = - 4
-2x = - 4
x = - 4/-2 = 2
Putting value of x in the equation 1
Y = - 3(2)
Y = - 6
relative minimum would be your awnser
