How do you do solving two-step equasions

The goal of solving two-step equations is to isolate the variable (get it by itself) and solve for the value using the following steps:

1. Add or subtract the constant term from both sides of the equation.

2. Multiply or divide the coefficient from both sides of the equation.

Step-by-step explanation:

Solving equations means using inverse (opposite) operations.  

subtraction - addition

multiplication - division

In order to get the variable by itself, you need to first get rid of the constant (the number by itself) by adding or subtracting from both sides of the equal sign. Then, you multiply or divide by the coefficient of the variable to solve for the variable.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
