This is a system of two linear equations.
Equation 1: ,4x+y=
Equation 2: 2x-7y=30
To solve the system by the method of substitution, the first step is to solve Equation 1 for y in terms of x. Remember to change the sign of a term when you move it to the opposite side.
Next substitute this expression for y in Equation 2 to get a single variable equation in x.
Expand the expression on the left hand side by using the distributive property.
Move the constants to one side and combine like terms.
30x=
Divide each side of the equation by the same number to get the value of x.
