solve for a.\n7a - 2b = 5a + b\n○ a = 2b\n○ a = 3b\n○ a = \\frac{3}{2}b\n○ a = \\frac{2}{3}b
Answer
Explanation:
Step1: Move terms with a to one - side
Subtract 5a from both sides: $7a - 5a-2b=5a - 5a + b$ $2a-2b = b$
Step2: Move the non - a term to the other side
Add 2b to both sides: $2a-2b + 2b=b + 2b$ $2a=3b$
Step3: Solve for a
Divide both sides by 2: $a=\frac{3}{2}b$
Answer:
$a=\frac{3}{2}b$
