Answer:
a + 4b - 24
Explanation:
Expand brackets. Each term in the brackets is multiplied by 4.
4( 1/4a) + 4(b) + 4(-6)
4/4a + 4b - 24
simply multiply 4 to the numbers in the brackets. If there is an unknown variable then write it as it is. Don't forget the to multiply the signs as well.
4 x 1/4a = 1a = a
4 × b = 4b
4 × -6 = -24
