To solve x + 1.4 = 2, subtract 1.4 from each side; x = 0.6
First, solve for y.y=-8xif x=2, then y=-16.
To solve -2+x=7, you need to isolate the variable x by adding two to both sides of the equation. -2+x=7 -2+x+2=x 7+2=9 x=9
The answer is x = 2.
If -x - 2 = 9, we can solve for x by first adding 2 to both sides: -x - 2 + 2 = 9 + 2 -x = 11. Next, multiply both sides by -1 to remove the negative and solve for x. -(-x) = -11 x = -11.
