Question

0.5(4−2a)=a−1.8 SOLVE FOR A PLZZZZZZZ HELPPP

Answer 1

0.5 (4 - 2a) = a - 1.8

a = 1.9

Answer 2

Step 1. Expand

2 - a = a - 1.8

Step 2. Add a to both sides

2 = a - 1.8 + a

Step 3. Simplify a - 1.8 + a to 2a - 1.8

2 = 2a - 1.8

Step 4. Add 1.8 to both sides

2 + 1.8 = 2a

Step 5. Simplify 5 + 1.8 to 3.8

3.8 = 2a

Step 6. Divide both sides by 2

3.8/2 = a

Step 7. Simplify 3.8/2 to 1.9

1.9 = a

Step 8. Switch sides

a = 1.9
