x+10=20 then you subtract 10 from both sides x=10
10
it means that x should equal 10. x + x = 20. x = 10
x = 20
-20 = -4x - 6x -20 = -10x -20 / -10 = -10x / -10 2 = x x = 2
x+10=20 then you subtract 10 from both sides x=10
10
it means that x should equal 10. x + x = 20. x = 10
1
20
x = 20
x = 20
-20 = -4x - 6x -20 = -10x -20 / -10 = -10x / -10 2 = x x = 2
what is the solution of x-5y=10 and 2x-10y=20
Well, darling, if you're asking me what times 10 equals 200, the answer is 20. It's simple math, sweetheart. Just divide 200 by 10 and you'll get your answer. Math doesn't have to be complicated, honey.
4x-5y=20 x-3y=10 becomes x=3y-10 plug that into the first equation: 4(3y-10)-5y=20 12y-40-5y=20 7y=60 y=60/7 If x=3y-10, then x=3(60/7)-10 x=180/7 - 70/7 x=110/7
x-6-x-4=10-x-10=10-xx=20
