What is the solution of: u-7+(-3)=-12
u - 10 = -12
add 10 to both sides
u = +10 -12
u = -2
u-7+(-3)=-12
u - 10 = -12
u = -12 + 10
u = -2
To solve the equation (u - 7) + (-3) = -12, follow these steps:
Step 1: Simplify the equation by combining like terms.
Start by removing the parentheses around (-3) and combine it with the -7 to get -10. The equation becomes:
u - 10 = -12.
Step 2: Isolate the variable term.
To obtain the value of u, we need to isolate it on one side of the equation. Since the u term is currently on the left side, move the -10 to the right side by adding 10 to both sides of the equation:
u - 10 + 10 = -12 + 10.
This simplifies to:
u = -2.
Hence, the solution to the equation u - 7 + (-3) = -12 is u = -2.
