You can first subtract 2 from 12 to get 10. Then when you bring 10 across the = sign, it becomes -10, so 42-10 is 32.

U can subtract 18 from each side of the equation.
Subtract two from both sides and you are left with X equals -5
Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
To solve -2 plus 5 equals, it's probably easier to start with the positive number and add the negative number to it. The equation will look like this: 5 + (-2) = Because you are adding a negative number, you actually have to subtract the 2, rather than add it, so your answer will be 3.
x=1, y=1

h+1.5=8.4 subtract 1.5 from both sides h=6.9
19 = f + 5 Subtract 5 from both sides: 14 = f
