Question

Using elimination method solve 4a+5b=2

Answer 1

Step-by-step explanation:

Step 1

Subtract 5b5b from both sides.

4a=2-5b4a=2−5b

Step 2

Divide both sides by 44.

\frac{4a}{4}=\frac{2-5b}{4}

4

4a

=

4

2−5b

Hint

Undo multiplication by dividing both sides by one factor.

Step 3

Dividing by 44 undoes the multiplication by 44.

a=\frac{2-5b}{4}a=

4

2−5b

Hint

Undo multiplication.

Step 4

Divide 2-5b2−5b by 44.

a=-\frac{5b}{4}+\frac{1}{2}a=−
