1) | x - 2| + 3 = 7
2) |x - 2| = 7 - 3
3) |x - 2| = 4
4) x - 2 = 4 and x - 2 = - 4. Then the answer is x - 2 = - 4

Answer:
x=13,y=0
Step-by-step explanation:
We are given a system of equations

For equation 1,square all terms to reduce it
√x²+√y²=169
x+y=13
Make x the subject as required by the question to use substitution method
x=13-y
Plug x=13-y into eqn 2
3(13-y)+2y=39
39-3y+2y=39
39-y=39
y=39-39=0
Plug y=0 into equation 1
x+0=13
x=0
