8. Solve the system of equations shown by substitution.
1 answer:
Answer:
J. (2, -3)
Step-by-step explanation:
1. Substitute y = x - 5 in for y in the other equation:
5x + 2(x - 5) = 4
2. Simplify:
5x + 2x - 10 = 4 (distributed the 2)
7x - 10 = 4
3. Isolate for x:
7x - 10+10 = 4+10
7x = 14
7x/7 = 14/7
x = 2
4. Plug the new x value into an equation and solve for y:
y = 2 - 5
y = -3
hope this helps!
