7x +3 = 5x + 25
2x + 3 = 25
2x = 22
x = 11
Answer:
x = -3
Step-by-step explanation:


Add 2/3 x to both sides: 
Subtract 8 from both sides: 
Multiply both sides by 3: 
Divide both sides by 11: 
Therefore, point of intersection between both lines is at point (-3, -1)
Steps to solve:
15 + 2a = 35
~Subtract 15 to both sides
2a = 20
~Divide 2 to both sides
a = 10
Best of Luck!
