Answer:
a + b
Step-by-step explanation:
1/2 (4a+6b) - 1/4 (4a+8b)
Because 1/2 * (4a+6) / 1 = 4a+6 / 2 So we can write it as:
= (4a+6b) / 2 - 1/4 (4a+8b)
Factor our common term 2:
= 2*(2a+3b) / 2 - 1/4*(4a+8b)
Cancel 2:
= (2a+3b) - 1/4*(4a+8b)
1/4*(4a+8b) can be write as: 1/4 * (4a+8b) / 1
= (2a+3b) - (4a+8b) / 4
Factor out common term 4, we got:
= (2a+3b) - 4(a+2b) / 4
Cancel 4:
= (2a+3b) - (a+2b)
Break the bracket:
= 2a+3b-a-2b
= 2a - a + 3b - 2b
= a + b

Hope this help you :3
