Answer:
m=0.7404, b=3.9117m=0.7404,b=3.9117
y=0.7404x+3.9117y=0.7404x+3.9117
x=18x=18
y=0.7404(18)+3.9117=17.2389y=0.7404(18)+3.9117=17.2389

Answer:
x=9
Step-by-step explanation:
Distribute:
3x+9-2x+2=5x-25
Combine like terms:
x+11=5x-25
Solve:
x-x+11=5x-x-25
11=4x-25
11+25=4x-25+25
36=4x
Divide by 9:
x=9.
Hope this helps :D
We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.
