Answer:
Look at the picture
Step-by-step explanation:
y = x^2 + 4 replace x and y
x = y^2 + 4 subtract 4 from both sides
x - 4 = y^2 sqaure root both sides

Answer:
15+7=22
Step-by-step explanation:
Set up the equations.
Answer:
Step-by-step explanation:
Step 1: Sum of angles on a straight line is 180
Step 2:
2x + 25 + y = 180
2x + y = 180 - 25
2x + y = 155 (1)
Step 3:
3x - 10 + y = 180
3x + y = 180 + 10
3x + y = 190 (2)
Step 4: Substract equation 1 from 2
3x + y - 2x - y = 190 - 155
x = 35
Step 5:
Substitute x in equation 1 to find y
2x + y = 55
2(35) + y = 155
70 + y = 155
y = 155 - 70
y = 85
