Question

Solve for a. 4a+5=2+3.25a

Answer 1

Answer:

$\boxed{\bold{a=-4}}$

Equation:

$\bold{4a+5=2+3.25a}$

Step By Step Explanation:

• Multiply Both Sides By 100

$\bold{4a\cdot \:100+5\cdot \:100=2\cdot \:100+3.25a\cdot \:100}$

• Simplify

$\bold{400a+500=200+325a}$

• Subtract 500 From Both Sides

$\bold{400a+500-500=200+325a-500}$

• Simplify

$\bold{400a=325a-300}$

• Subtract 325a From Both Sides

$\bold{400a-325a=325a-300-325a}$

• Simplify

$\bold{75a=-300}$

• Divide Both Sides By 75

$\bold{\frac{75a}{75}=\frac{-300}{75}}$

Simplify

$\bold{a=-4}$

Answer 2

Answer:

$a=-4$

Step-by-step explanation:

$4a+5=2+3.25a$

$4a\cdot \:100+5\cdot \:100=2\cdot \:100+3.25a\cdot \:100$

$400a+500=200+325a$

$400a+500-500=200+325a-500$

$400a=325a-300$

$400a-325a=325a-300-325a$

$75a=-300$

$\frac{75a}{75}=\frac{-300}{75}$

$a=-4$
