Question

solve this using substitution y=0.35x+40
                                                y=0.10x+50 
Please!

campbell_st · Answer

well equate the equations 

0.10x + 50 = 0.35x+ 40

subtract 0.10x from both sides

50 = 0.25x + 40

subtract 40 from both sides

10 = 0.25x 

I'll leave you to divide both sides of the equation by 0.25 to get the answer. 

Hope this helps.

putting the value of y from first equation in second equation
so
0.35x+40=0.10x+50
taking x terns one side and all others on other side
0.35x-0.10x=50-40
0.25x=10
x=10/0.25
=40 :)
