30 = 20+x
x = 10
Answer:
[tex]x=10[/tex]
Step-by-step explanation:
[tex]5(2x+6)=-4(-5 -2x) + 3x[/tex]
[tex]\longrightarrow[/tex] Use the distributive property to multiply 5 by 2x+6, and -4 by -5 - 2x.
[tex]10x+30=20+8x+3x[/tex]
[tex]\longrightarrow[/tex] Combin 5x and 2x to get 11x:-
[tex]10x+30=20+11x[/tex]
[tex]\longrightarrow[/tex] Subtract 11x from both sides:-
[tex]10x+30-11x=20[/tex]
[tex]\longrightarrow[/tex] Combine 10x and -11x to get -x:-
[tex]-x+30=20[/tex]
[tex]\longrightarrow[/tex] Subtract 30 from both sides:-
[tex]x=20-30[/tex]
[tex]\longrightarrow[/tex] Subtract 30 from 20 to get -10:-
[tex]-x=-10[/tex]
[tex]\longrightarrow[/tex] Multiply both sides by -1:-
[tex]x=10[/tex]
