X is 16 so turn everything into a equation
Answer:
x = 5 and y = -5
Step-by-step explanation:
You can use algebra or graphing to solve this. I will be using algebra, with substitution.
Step 1: Move the 5 over in the 1st equation
3x + 2y = 5
x = y + 10
Step 2: Substitute in x
3(y + 10) + 2y = 5
Step 3: Distribute
3y + 30 + 2y = 5
Step 4: Combine like terms
5y + 30 = 5
Step 5: Move the 30 over
5y = -25
Step 6: Divide both sides by 5
y = -5
Step 7: Plug it back in into an original equation to find x
x = -5 + 10
x = 5
Answer: 5
Step-by-step explanation:
8-2b=-2
8-2b-8=-2-8
-2b=-10
-2b/-2=-10/-2
b=5
It is an irrational number
