Question

Solving Systems By Substitution
y=3x+11
y=-2x+1

Answer 1

y equals 3x + 11
y also equals -2x + 11
We can just say \(3x + 11 = -2x + 1\)

Solve for x.

Answer 2

i need alittle more assistance

Answer 3

Okay. Aight.

\(\Large \color{Black}{\Rightarrow 5x + 11 = 1 }\)
Adding 2x to both sides.

\(\Large \color{Black}{\Rightarrow 5x = -10 }\)
Subtracting both sides by 11.

\(\Large \color{Black}{\Rightarrow x = -2}\)
Dividing both sides by 5.

Answer 4

Now y = 3x + 11
So, y = 3(-2) + 11
y = -6 + 11 = 5
