Answer:
51
Step-by-step explanation:
Given the following question:
[tex]20-5y+2x[/tex]
[tex]x=8[/tex]
[tex]y=-3[/tex]
Substitute and solve using PEMDAS:
[tex]20-5y+2x[/tex]
[tex]20-5(-3)+2(8)[/tex]
[tex]5\times-3=-15[/tex]
[tex]20--15+2(8)[/tex]
[tex]2\times8=16[/tex]
[tex]20-(-15)+16[/tex]
[tex]20--15=35[/tex]
[tex]35+16=51[/tex]
[tex]=51[/tex]
Your answer is "51."
Hope this helps.
