Answer: x=20
Step-by-step explanation:
Answer:
one solution: (2.5, 0)
Step-by-step explanation:
Given the following system of equations;
y = 2x - 5
-8x - 4y = -20
To find the solution to the equations, we would use the substitution method;
Substituting eqn 1 into eqn 2, we have;
-8x - 4(2x - 5) = -20
-8x - 8x + 20 = -20
-16x + 20 = -20
-16x = -40
x = 40/16
x = 2.5
Next, we would determine the value of y;
y = 2x - 5
y = 2(2.5) - 5
y = 5 - 5
y = 0
