| To find the point of intersection of the lines y = 47x – 37 and y = -13x + 23, we will solve a system of these equations.
System of equations:
y = 47x – 37;
y = -13x + 23.
To solve the system, we use the substitution method. Substitute -13x + 23 for the variable y in the first equation.
System of equations:
-13x + 23 = 47x – 37;
y = -13x + 23.
Let’s solve the first equation of the system and get:
-13x – 47x = -37 – 23;
x (-13 – 47) = -60;
-60x = -60;
x = -60: (-60);
x = 1.
System of equations:
x = 1;
y = -13x + 23 = -13 * 1 + 23 = -13 + 23 = 10.
