Answer:
Here's the simplest example possible: let's say x + y = 3 and x - y = 1. Solve the second equation for x by adding y to both sides: (x - y) + y = 1 + y. So x = 1 + y. Take that value of x, and substitute it into the first equation given above (x + y = 3).
Answer:
D. 3 1/4
Step-by-step explanation:
Answer:
A. 2
B. 10/3
C. 8/3
D. 2/3
Step-by-step explanation: put the whole #and make it into a fraction like this e.g.
6/1 • 1/3 = 6/3 simplifies to 2
(2x-6) + 4(x-3) {distribute 4 out and expand problem}
2x+6+4x-12 {combine like terms}
6x-6 {your answer}
