2x+5(-0.5x+6)=40
2x-2.5x+30=40
-0.5x=10
x=-20
y=-0.5(-20)+6
y=16
These two are true:

Answer:
Step-by-step explanation:
hello
calculate x : 3x+2 =5
means : 3x+2-2 =5-2
3x = 3
so : x = 3/3 =1
1 is the element in domain has the image 5 under function f(x)= 3x+ 2
A=7
you would start with the equation 3a+4=a+18
to solve you try to get a by itself. you would first subtract an a from each side to get all the a's together- 2a+4=18
then you would subtract 4 from each side to get the 2a by itself- 2a=14
finally to get a by itself you divide each side by 2, to get a=7
