Write the equation
10 + x + 19 + x = 11
10 + x +11 = 19 + x
11 + 19 + x = 10+ x
10+ x - 19 + x = 11
Find x
Set up the equation for solving for x
x - 4 + 2x - 2 = 12
x - 4 - 2x - 2 = 12
2x - 2 - 12 = x - 4
x - 4 + 12 = 2x - 2
x =
set up the equation for solving for x
1 + 3x - 6 = 6x - 2
1 + 3x + 6 = 6x - 2
1 + 3x + 6x - 2 = 6
6x - 2 + 6 = 1 + 3x
2x + 19 + x + 7 = 12
12 - x + 7 = 2x + 19
12 + x + 7 = 2x + 19
x + 7 + 2x + 19 = 12
Write the correct equation or formula
2x-5 + 2 = 21+ x
2x-5 + 2 +x = 21
2x-5 + 2 = 21
21 + 2 +x = 2x - 5
x + 19 + 5 + x + 20 = 28
x + 19 - 5 - x + 20 = 28
x + 19 + x + 20 = 28 + 5
x + 19 - x + 20 = 20 - 5
