Start with the second part of your equation
4x + 10 = 18
4x = 8 Subtract 10 from both sides
x = 2 Divide by 4 on both sides
Now substitute 2 for x on the first part of your equation
2 (2) - 5y = 11
4 - 5y = 11 Simplify
-5y = 7 Subtract 4 from both sides
y = -7/5 or -1.4 Divide by -5 on both sides
-4 plus 10 equals 6.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
x=10
12 + 10 + 11 equals 33
-10 plus 10 equals 0.
61
10 plus 10 equals 20 20 divide by 10 equals 2 2 plus 10 equals 12
10 + 10 + 10
A equals 4 because 4 plus 6 is 10 or 10 minus 6 is 4.
19 plus 10 equals 29.
49 plus 10 equals 59.
