This system has one solution. Here are my steps to solving this problem:
y=x+1
2(x+1) - x = 2
2x +2 - x = 2
2x - x + 2 = 2
x + 2 = 2
- 2 - 2
----------------
x = 0
y = 0 + 1
y = 1
I hope this helps you!

Step-by-step explanation:
angle of triangle is 180°
the angle beside 70° is 70°also because it has mention it is an isosceles triangle so that the two angle must be same

Answer:
The number is 14
Step-by-step explanation:
Let n be the number. We can set up an equation:
2(n+20)=5n-2
Distribute the left side
2n+40=5n-2
Move like terms to one side. Note that the sign flips when we move a term from one side to the other.
40+2=5n-2n
42=3n
Divide both sides by 3
n=14
