Answer:

$a =8$

Step-by-step explanation:

$-7 - 3a = 1 - 4a$

add $3a$ to both sides

$-7 - 3a + 3a = 1 -4a + 3a \\-7 = 1 -a$

add $-1$ to both sides

$-7 - 1 = 1 - a -1\\-8 = -a$

multiply both sides by $-1$

$-8 * (-1) = -a * (-1) \\8 = a$

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 p

nikklg [1K]

X = large boxes and y = small boxes

x + y = 70.....x = 70 - y
60x + 65y = 4300

60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs

x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
