Answer:
(-7, -10)
Step-by-step explanation:
Solve for x and y in double variable equation
y = 2x + 4
y = x - 3
y = x - 3, plug in to first equation
x - 3 = 2x + 4
x = -7
y = -7 - 3
y = -10
(-7, -10)
Answer:
x=25
Step-by-step explanation:
First, we add all like terms. Then, we solve for x.
We can rearrange some things because order does not matter with addition. Next, we just use basic equation solving techniques.
