Solve the following for `x` : `-7.5=5.2+x`
The general procedure for solving an equation in one variable is:
(1) Eliminate grouping symbols, usually using the distributive property
(2) Collect like terms on both sides of the equation
(3) Get the terms with variables on one side of the equation, collecting like terms as needed.
(4) Undo addition/subtraction.
(5) Finally undo multiplication/division.
In this case there are no grouping symbols and there is only one term with a variable. So we undo the addition to get the term with the variable by itself:
So, `x=-12.7` is the solution. Checking we see that indeed `5.2+(-12.7)=-7.5` as required.
all you have to do is subtracy 5.2 to the other side. so -7.5-(5.2)=X.
so the answer is -12.7
