Ineed like right now its do tomorrow 1st period and can you explain it to me and

6 3/4 +x= 5 1/2

subtract 6 3/4  from each side

x = 5 1/2 - 6 3/4

get a common denominator

x = 5 2/4 - 6 3/4

take larger - smaller and take the sign of the larger

x = -(6 3/4 - 5 2/4)

x = - 1 1/4

Choice C

step-by-step explanation:

the answer is 128

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
